I have now updated PEP 408 accordingly (i.e. rejected, but with a
specific note about regex).

And (since Alex Gaynor brought it up off-list), I'll explicitly note
here that I'm taking your approval as granting the special permission
PEP 399 needs to accept a C extension module without a pure Python
equivalent. Patches to *add* a pure Python version for use by other
implementations are of course welcome (in practice, I suspect it's
likely only in PyPy that such an engine would be fast enough to be
usable).

Regards,
Nick.
