Unpound ======= Perl input filter for debugging by uncommenting debug statements. Lets you write things like: #debug# print "This code is not normally even evaluated\n"; Ordinarily not even evaluated, so there is no performance hit in checking for debugging variables, but then you can run $ perl -MFilter::Unpound=debug script.pl and suddenly those lines become active. Multi-line comments, shortcuts for simple prints, etc are supported.
