I'm afraid the answer at the moment is no.
The code is stabilized to the point where I would consider doing it,
now. If you are interested in trying yourself, you can look at
boost/libs/python/src/converter/builtin_converters.cpp and
boost/boost/python/converter/builtin_converters.hpp.
However, I'm not completely sure what the best interface would be. In
particular, should enums really be exposed as Python Ints? Wouldn't it
be better to expose a Python subclass of Int whose str() and repr()
functions return user-friendly names?
I'd like to consider these things (and would love some feedback) before
implementing enum support.
