When building grunt with flags set to detect variables that get a value but
then are unused, there are 5 instances that causes error (unused variable).
In most cases it's enough to simply remove the variable. Other instances,
is better to simply use the variables (one instance it's a return value, on
the other instance using the variables makes code more readable).
