Use when writing or reviewing Go code that iterates over slices, arrays, maps, or channels with range, uses break inside switch/select within loops, or places defer calls inside loops.\n---\n\n# Go Control Structures\n\nRules for avoiding common mistakes with range loops, break statements, and defer in Go.\n\n## Range Loops Copy the Value Variable\n\nThe value variable in a range loop is a **copy** of the element. Mutating it does not modify the original collection.\n\n**Wrong** -- mutates only the copy:\n```go\nfor _, a := range accounts {\n    a.balance += 1000 // has no effect on the slice\n}\n```\n\n**Correct** -- access via index:\n```go\nfor i := range accounts {\n    accounts[i].balance += 1000\n}\n```\n\nRules:\n- When you need to **mutate** struct elements in a slice/array, use the index variable (`for i := range`), not the value variable.\n- If the slice already holds pointers (`[]*T`), mutation through the value variable works, but be aware of CPU cache implications for large collections.\n- Read-only iteration with the value variable is fine.\n\n## Range Expression Is Evaluated Once\n\nThe expression passed to `range` is copied once before the loop starts. The loop iterates over this snapshot.\n\n### Slices\n\nAppending to a slice during `range` does not extend the iteration -- the loop uses the original length:\n\n```go\ns := []int{0, 1, 2}\nfor range s {\n    s = append(s, 10) // loop still runs exactly 3 times\n}\n```\n\nA classic `for i := 0; i < len(s); i++` re-evaluates `len(s)` each iteration and **would** loop forever with the same append logic.\n\n### Channels\n\nReassigning the channel variable inside the loop body has no effect -- `range` iterates over the channel captured at the start:\n\n```go\nch := ch1\nfor v := range ch {\n    ch = ch2 // has no effect; range still reads from ch1\n}\n```\n\n### Arrays\n\n`range` copies the **entire array** (not just a slice header). Modifications to the original array are not visible through the value variable:\n\n```go\na := [3]int{0, 1, 2}\nfor i, v := range a {\n    a[2] = 10\n    if i == 2 {\n        fmt.Println(v) // prints 2, not 10\n    }\n}\n```\n\nTo see mutations, either:\n- Access the element via index: `a[i]`\n- Range over a pointer: `for i, v := range &a { ... }`\n\nRanging over `&a` avoids the full array copy -- prefer this for large arrays.\n\n## Pointer to Range Variable Trap\n\nThe range value variable has a **single address** across all iterations. Storing `&v` always stores the same pointer, which ends up pointing to the **last** element.\n\n**Wrong** -- all map entries point to the last customer:\n```go\nfor _, customer := range customers {\n    s.m[customer.ID] = &customer // same address every iteration\n}\n```\n\n**Fix 1** -- local copy:\n```go\nfor _, customer := range customers {\n    current := customer\n    s.m[current.ID] = &current\n}\n```\n\n**Fix 2** -- pointer via index:\n```go\nfor i := range customers {\n    customer := &customers[i]\n    s.m[customer.ID] = customer\n}\n```\n\nRules:\n- **Never** store `&rangeValueVar` across iterations. The agent must flag this pattern in reviews.\n- Apply the same caution with slices and maps alike.\n\n## Map Iteration Assumptions\n\n### No ordering guarantees\n\nMaps in Go provide:\n- No sorting by key\n- No preservation of insertion order\n- No deterministic iteration order (order varies between runs)\n\nNever write code that depends on map iteration order. If ordered traversal is needed, collect keys into a slice, sort it, and iterate over the sorted slice.\n\n### Inserting during iteration is non-deterministic\n\nA new map entry added during iteration **may or may not** be visited in that same iteration. The behavior varies per entry and per run.\n\n**Wrong** -- unpredictable results:\n```go\nfor k, v := range m {\n    if v {\n        m[10+k] = true // may or may not appear in this iteration\n    }\n}\n```\n\n**Correct** -- read from original, write to a copy:\n```go\nm2 := copyMap(m)\nfor k, v := range m {\n    m2[k] = v\n    if v {\n        m2[10+k] = true\n    }\n}\n```\n\nRules:\n- Deleting map entries during iteration is safe (deleted keys will not appear later).\n- Inserting entries during iteration produces non-deterministic results. Separate the read map from the write map when adding entries.\n\n## Break Terminates the Innermost for/switch/select\n\n`break` inside a `switch` or `select` that is inside a `for` loop breaks the **switch/select**, not the loop.\n\n**Wrong** -- break exits switch, loop continues:\n```go\nfor i := 0; i < 5; i++ {\n    switch i {\n    case 2:\n        break // breaks the switch, NOT the for loop\n    }\n}\n```\n\n**Correct** -- use a label:\n```go\nloop:\n    for i := 0; i < 5; i++ {\n        switch i {\n        case 2:\n            break loop // breaks the for loop\n        }\n    }\n```\n\nSame pattern applies to `select` inside a loop:\n\n```go\nloop:\n    for {\n        select {\n        case <-ch:\n            // handle\n        case <-ctx.Done():\n            break loop // breaks the for loop, not select\n        }\n    }\n```\n\nRules:\n- Whenever `break` appears inside a `switch` or `select` nested in a loop, verify that the intent is to break the inner statement. If the intent is to exit the loop, require a labeled break.\n- `continue` with a label can similarly target an outer loop.\n- Labeled breaks are idiomatic Go (used in the standard library, e.g., `net/http`).\n\n## Defer Inside a Loop\n\n`defer` executes when the **surrounding function** returns, not at the end of each loop iteration. Placing `defer` directly in a loop body defers all calls until the function exits, leaking resources for the loop's lifetime.\n\n**Wrong** -- file descriptors stay open until `readFiles` returns:\n```go\nfunc readFiles(ch <-chan string) error {\n    for path := range ch {\n        file, err := os.Open(path)\n        if err != nil {\n            return err\n        }\n        defer file.Close() // not called until readFiles returns\n        // ...\n    }\n    return nil\n}\n```\n\n**Correct** -- extract the body into a function so `defer` fires each iteration:\n```go\nfunc readFiles(ch <-chan string) error {\n    for path := range ch {\n        if err := readFile(path); err != nil {\n            return err\n        }\n    }\n    return nil\n}\n\nfunc readFile(path string) error {\n    file, err := os.Open(path)\n    if err != nil {\n        return err\n    }\n    defer file.Close()\n    // ...\n    return nil\n}\n```\n\nAn anonymous closure also works:\n\n```go\nfor path := range ch {\n    if err := func() error {\n        f, err := os.Open(path)\n        if err != nil {\n            return err\n        }\n        defer f.Close()\n        // ...\n        return nil\n    }(); err != nil {\n        return err\n    }\n}\n```\n\nRules:\n- Flag any `defer` that appears directly inside a `for`/`range` loop body. Wrap the loop body in a helper function or closure so `defer` fires per iteration.\n- This applies to any resource cleanup (file handles, locks, DB connections, HTTP response bodies).\n","tagline":"Enforces correct usage of Go control structures including range loops, break statements, and defer in loops.
