Unless it begins with a 0 (that's what's documented today -- read the docs
<wink>).

The docs say you can't use backreferences for groups higher than 99.
> If there are exactly 3 digits and you have at most 99 groups, it's an

If we make the meaning depend on the number of preceding groups, we may as
well emulate *all* of Perl's ugliness here.
