++ for mentioning the -n Bash operator, I wasn't aware of the string testing operators in Bash. I was shocked to find out that Bash uses == for strings and -eq for integers.

I found a stackoverflow node that deals with the empty string issue and the best answer for Perl seemed to be to use the length function.

return unless length $str;
