Yes. Done it been there etc. Some applications... most notably
MAPPER from Sperry - a popular mainframe app, have a problem when
things refer to themselves... like Int = Int + 1, where a 3rd
intermediary is necesery.

VB/A/S Has no problems there. *All* versions of basic to my knowledge
have been incestuous.. that is been able to refer to themselves.

The function  will be resolved before passing the parameter to the
function/sub.
