LOCAL variable names should be short, and to the point.  If you have
some random integer loop counter, it should probably be called ``i``.
Calling it ``loop_counter`` is non-productive, if there is no chance of it
being mis-understood.  Similarly, ``tmp`` can be just about any type of
variable that is used to hold a temporary value.
