ExtensionType vs ExtensionOldType

[π <sun...@gm...>]

Hello PyCXX people,

I am very glad to find this framework,  I have been spending some time digging through the source code attempting to understand how it does its magic.

I'm confused by the existence of new-style classes and old-style classes.

For example, in test_simple.py, both of these are tested?

What are these entities?

Did someone create a new mechanism for wrapping C++ classes as Python Types that was not backwards compatible (whatever that may mean), and hence both are now coexisting in the CodeBase?

PS looking through the source code, I notice that vast amount of compacting is possible through preprocessor macros and Variadic Templates.  I'm in the process of refactoring, mainly so that I can gain some familiarity with the CodeBase and present certain sections in a way that my brain can parse more easily.  I've uploaded some of my changes to http://mathpad.wikidot.com/pycxx — the links at the bottom of this page go to various modifications.
