Actually, I've rethought taking this grep issue to clpm or perlmonks.  Think
I'll subscribe to p5p and wade in.  That's where an issue such as this really
belongs.  That's where I would send a patch for the recommended change to, so,
why not?

Wish me luck!

I like Michael Schwern's quote from the p1p porter's list (Schwern recently
became pumpking for Perl 1, it is a joke, but he really is updating Perl 1 to
fix bugs and make it so that it compiles on modern systems).  

It was something like:

        "No syntax changes, p5p is 10 years down, first swirling vortex on your
right."
