Okay . . . I guess that sorta makes sense.  Of course, I've never used \1
in Perl, nor seen anyone else do so either, so until you mentioned it I
had entirely forgotten that was an option there either.

Both languages would be better off without that syntax, and just stick
with $1 instead, I think.

I wouldn't really call \1 a "Perlism", given that the way I've always
seen it done is with $1 instead.  If it's a Perlism despite its lack of
general usage, I'd say it's every bit as much a Rubyism.
