Yes, what you suggest is normally the best approach.

Unfortunately these are functions that are called by other built-in
routines in the iTools library, and I don't have the fortitude to
attempt to duplicate that entire code base, change names, change all
references to the updated functions, etc.

I limit this practice to a handful of routines.

Cheers, Ken
