RMGir, meet B::Xref. B::Xref, meet RMGir :-)

I've published elsewhere a little script which parses the output of B::Xref to catch unused subs. if you just change the last four lines to:

foreach my $sub (keys %subused) {
    next if exists $subdef{ $sub };
    print "UNDEFINED SUB: $subused{ $sub } $sub\n";
}

you have something that will catch your handelNewYear error :-)

Thanks!

I think both the unused and undeclared options look pretty useful.

Your post is a reply to Warnings for unused subs, an interesting thred I'd missed.

PS: I liked that side trip to Re: Re: ESMTP, linefeed and <CRLF> before you fixed your link; it made me wonder if I'd accidentally gotten decaf this morning :)
