This reminds me: is it recommended to wrap custom macros in a package? It hadn’t occurred to me to do it before, but I now I see it’s pretty common in pg/macros.

Is there anything else that I should be on the lookout if declaring a package name in my macro file? For instance, how can I get my subs to still appear in the ‘main’ namespace so they don’t have to be qualified to call them from a problem file? From what I can see in PG, some macro packages (PGCommonFunctions) switch back to main and add subs there, while others (currencyContext.pl) seem to do it with 'main::PG_restricted_eval’.
