I'm willing to go along with that (especially given your report of AppEngine's experience with the "labs" namespace).

Can we class this as a pronouncement on PEP 408? That is, "No to adding a preview namespace, but yes to adding regex directly for 3.3"? Yup. We seem to have a tendency to over-analyze decisions a bit lately (witness the hand-wringing about the hash collision DoS attack).

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.
