Once the compiler is translated to C, it might be worth considering
making SRE available as a standalone library for use outside of
Python.  Most other regex libraries either don't do Perl's extensions,
or they don't do Unicode.  Bonus points if you can get the Perl6 team
interested in it.

Hmm... here's an old problem that's returned (recursion on repeated
group matches, I expect):

>>> p=re.compile('(x)*')
>>> p
<SRE_Pattern object at 0x8127048>
>>> p.match(500000*'x')
Segmentation fault (core dumped)
