Redundant range variable shadowing

Reports redundant variable shadowing inside a for range loop, such as x := x, that was previously used to capture the loop variable for a goroutine or closure.

Starting with Go 1.22, each for range iteration uses a fresh loop variable. Because of this, the extra x := x assignment no longer changes the behavior and can be removed.

Example:

for _, x := range xs {
    x := x
    go func() { done <- x }()
}

To simplify the code, use the Remove unneeded declaration quick-fix.

After the quick-fix is applied:

for _, x := range xs {
    go func() { done <- x }()
}
