Hi sm@sh,

"1"==1, "1" eq 1, and looks_like_number(1) and looks_like_number("1") are all true in Perl. The StackOverflow thread that clueless newbie linked to already contains some excellent answers - especially choroba and ikegami's answers explain the caveats of peeking under the hood. That's why I recommended looking for a different solution to your problem than figuring out difference between 1 and "1".

Regards,
