No, unfortunately that doesn't work either. A regex match in scalar context returns 1 or 0. It needs to be called in list context to return the value.
>perl -E"print 'foo'=~/(o+)/;" oo
>perl -E"print scalar 'foo'=~/(o+)/;" 1

[Lady_Aleena]: LanX, I just never thought I would be explaining perl regex to others. It is usually others explaining why a regex isn't working to me.
[Discipulus]: congratulations shmem! (was my last upvote? ;=)
