in reply to How a script becomes a module
I've been using this technique and found it helpful for
testing, among other things. Today I hit a snag while
packaging my code with PAR. After a bit of debugging
I discovered that packaged files don't have an empty
caller so to make PAR friendly modulinos use something like:
__PACKAGE__->run() if !caller() || caller() eq 'PAR';
