He's right, its not a bug. Perl is rightly informing you that you used $g
only once. However his suggested fix is less than ideal. Its pretty much
tanamount to "don't use -w with -s".

However, the only other fix I can think of, don't make "used only once"
warnings for variables in package main when -s is in use, might not be
ideal either.

But I've never used -s in real code, so I can't really judge.

Maybe as a quick solution, on the perlrun manpage's "-s" description,
note what might happen when one uses -w, and how to workaround.

Here's a patch for perlrun to clear this up.
