Thanks, it works.

Now, how do I deal with overloaded constructors? . . . or overloaded
functions in general (I guess I could just give these different
names, but with constructors you don't have choice in name . . . or
should I wrap them in some make_class structure ?)

Hmm, this looks to me as if it could be more trouble than it's worth,
as I would somehow need to get template argument information into the
second (string) argument of the python::class_builder<> constructor.
Is there a neat way of dealing with this ?  (Maybe some trait trick, or
a template specialization . . . nothing truly simple comes to mind).
