Re: Strange Regex Behavior

Intriguing. If you quote the $1, you get the expected output. Quite what that tells us I'm not sure.

Update: this also works:

        a => ($b =~ /(\d+)/ ? 0+$1: 0),

As does this:

        a => ($b =~ /(\d+)/ ? do{ print $1; $1 }: 0),
[download]

But not this:

        a => ($b =~ /(\d+)/ ? do{ $1 }: 0),
[download]

Interesting. Similar to your +0, this seems to work: `a => ($b =~ /(\d+)/ ? "$1" : 0),` Could this be a Perl bug?	[reply] [d/l]

It certainly looks that way to me.
