perl -v will show the version of Perl you are running.

As for your regexp question, you are missing a backslash (\) before the letter "W". So, the propper line would be 

} elsif (/[\W_]/) { # other chars

That would match anything that is not a number (0-9) or a character - but the characters a-z are captured by the if higher up in the code. (Note that this will have problems if input contains Unicode characters)...
