I was just looking at this problem, and creating a bare-bones, no safety belts version for use in the stdlib (no patch yet) which decreases Enum creation from 14x slower to only 6x slower. (Comparing to a class with simple attributes.)
Not sure if that's enough improvement, though.
If it needs to be even faster, a C version of that simplified Enum shouldn't be too hard. Anyone that uses the _simple_enum, though, should have a test that uses the full Enum and compares the two to make sure nothing got lost in translation.
