Yeah, I don't think it works with PEP 395 in its current state. But
then, I'm not sure 395 will work at all in its current state -
definitely a work in progress, that one. However, I'll definitely keep
this aspect in mind next time I update it - even if they don't use the
same mechanism, they should at least be compatible proposals.

Cheers,
Nick.
