    background: Add exception to no-loop-func rule
    
    Modifying variables from an outer scope in functions created in a loop
    is considered problematic by eslint, because the variable value in the
    resulting closure is often not what the coder intended.
    
    In this particular case however, the scoping is correct, so add a comment
    to disable the rule locally.
