You ask for a way to bind a C++ member function to a python method.
But a member is always a member of some object, so MyType provides one.
Both, MyType as well as MyType::func are placeholders for your own code.

Indeed. You have to write that yourself, i.e. a function to extract
a MyType pointer (again, placeholder for your own object pointer)
from the python wrapper through which the member function is to be invoked.

Boost.python does all that for you automagically...
