Pattern: Reference to loop variable from within nested function
Issue: -
Checks for references to loop variables from within a function literal inside the loop body. It checks only instances where the function literal is called in a defer or go statement that is the last statement in the loop body.
Example of incorrect code:
func _() {
var ctx, cancel = context.WithCancel()
// this return statement may be reached without using the cancel var
}Example of correct code:
func _() {
ctx, cancel := context.WithCancel()
defer cancel()
}
