All Perl questions are simple :-)

Because !=~ isn't a comparison operator? You will kick yourself.... 


While I'm at it, don't put commas in qw(), it won't work (at least, it will,
but not in the way you intend - 'perl -w' and 'use strict;', and all will
become clear!). Your if statement won't work either - it looks like you're
evaluating @array in scalar context, which isn't what you want (it gives you
the cardinality of the data). Use map(){} instead, if you can 'require
5.005;' (or is it 5.004? can't remember...). Otherwise, foreach (@array){}
is what you want.
