I was wondering why so many people in the MacPerl world use the single-quote
instead of the double-colon as the package separator.  Is it just a needless
historical relic from the Perl 4 days, or is there some style guide out there
that I don't know about?  David's certainly not the only person who does it.

I suppose it fits with the .pl extension on libraries and the require()ing
thereof. =)
