[C++-sig] Boost.Python at runtime

Has anyone every used or even tried to use Boost.Python to dynamically
create python types at runtime (instead of the standard compile time
method)?
I am working on an very large extensible C++ class library that has a
reflective interface that I can extend as much as I need. So instead of
trying to create an enormous wrapper at compile time (that would be
quickly out of date) I have been investigating the possibility of
dynamically creating the python class/type wrappers on demand.
So for example if I discovered at run-time that I wanted a wrapper for a
class Hello I would:
- Ask Hello's reflective interface for information about the class and
it's bases
- Create an associated boost.python class object
- For each method Hello reports
- add method to the wrapper class using signature and method info
from Hello
I would also need to handle registering associated smart pointers, etc.
The details are definitely complex, but before I get to far into it I
was wondering if anyone had done anything similar or had tried and could
tell me how it went or if it is impossible with the current system.
Thanks,
Allen
