Obviously you're thinking of $00, $010, etc as result holders after regexp match.
However $0 does not have any relation to regular expression.
And $00 name was used by me as global variable which is a "variation" of $0.
like $i and $i0.
Although - not a big deal actually, but I would recommend to return old behaviour, so to improve backward compatibility with older perls.
Some my scripts broke, so there is a possibility that I am not the only one person on planet who happen to use $00 variable name.
