in reply to True or False? A Quick Reference Guide
It's worth mentioning this tidbit I picked up from HOP: '0 but true' is a special-case that will not issue a warning when used in a numeric context.
$ perl -we 'print "0 but true" + 2' 2 $ perl -we 'print "0 but actually true" + 2' Argument "0 but actually true" isn't numeric in addition (+) at -e lin +e 1. 2
