Hi,

what's the recommended way to check if an object instance is an instance of
my extension class
in C++ code?

I'm currently doing a very ugly

#define isMyExtensionClass(pyobj) (strcmp(pyobj->ob_type->tp_name,
"MyExtensionClass") == 0)

on PyObj* pyobj.

I bet there is a better way but just can't seem to find it.
