Yes, I do understand what globals are and why one may want to use
them. I do actually use them, albeit sparingly. My conceptual problem
here is with the persistence of global variables in the IDE once the
stack or suite of stacks that used them has been purged from memory.

In your example, can you think of a reason for the "find" string to
persist after you have closed the suite of stacks that initialized and
used the find handler and you've gone on to work on another project?
