L~R:
perl -e "use warnings; print qq{yeah$/} if 'p2p' == 'f2b'; print 'p2p' + + 0" Argument "f2b" isn't numeric in numeric eq (==) at -e line 1. Argument "p2p" isn't numeric in numeric eq (==) at -e line 1. Argument "p2p" isn't numeric in addition (+) at -e line 1. yeah 0
Non-numeric arguments are treated as 0 in numeric operations. == is a numeric comparision operator, its string equivalent being eq.
I remember reading somewhere (maybe the camel or llama book) that numbers in string representations may have a newline character after them, which would explain why you don't need to chomp. I couldn't find the passage, though.
