The fundamental issue here is that Python classes don't follow the same
semantics as CLR classes.  They are, for instance, mutable after
construction in ways that CLR classes are not.  In order to expose a Python
class directly to the CLR, it would have to be "frozen" in some manner, and
you might prefer to be able to specify the types of the parameters instead
of dealing with everything as "object".  This would require some sort of
non-Python syntax to accomplish.  Fortunately, there already is such a
thing: a CLR interface.  Define an interface in an external assembly and you
can derive from it in Python.  Your CLR classes can then access the Python
code through the interface.
