That, in turn, is because nobody has contributed code to make that work.
My guess is that people either don't need it, or find it too difficult
In any case, it is an important point that such a specification is
likely dead if the standard library doesn't support it throughout,
from start. So for this PEP, the same criterion likely applies: it's
not sufficient to specify an interface, one also has to specify
(and then implement) how that affects modules and types of the

If you are curious, try adding such a feature to re some time. I
expect that implementing it would be quite involved. I wonder what
Fredrik Lundh thinks about providing such a feature.
