Awesome, thanks for the advice. Finding a better way to get the callers was on my list of things to improve but I hadn't figured out a good way to accomplish this. In fact, IIRC, I think the code breaks if there are nested calls. I will definitely study this and see if I can get your suggestion incorporated.

I think I probably had Modern::Perl at some point which automatically inserts those pragmas. I must have accidentally deleted it. Thanks!
