[C++-sig] Boost.Python type registry

[Giovanni Beltrame]

Hello everybody,
I am trying to understand how the Boost.Python type registry works...

What I want to do is, given a python object (let's say a PyObject*), determine
its wrapper C++ type_info.
Theoretically, what I want to do is going name->PyObject->C++ type. Notice
that the traditional extract<T> won't work for me as I want to determine which 
type is being wrapped.

I know Boost.Python is doing this internally in some way, but I haven't 
figured it out yet.

Can anybody help?

Thanks in advance,
