I think you can write wrapper functions which abstract the details.
We'd want this anyway so we can turn Python exceptions into C++
exceptions.

boost::python basically does all this already, but I've been assuming
we'd roll our own.

I think the wrappers would be pretty thin, and there'd be no runtime hit
to speak of.
