Glancing at the branch and the 2 lines you mentioned.

You have a comment with a link for python 2.3 documentation.
Yet you have python 3.10 code included elsewhere (and openscad itself 
requires the modern spec C++17, so I assume your aim is at current versions)

https://docs.python.org/3.10/extending/newtypes.html
is the equivalent doc for that.

I am not experienced in defining PyType objects in C, but notice 
syntactical discrepancies, missing "static" on dealloc, use of 
typecasted malloc rather than PyType_GenericAlloc()
https://docs.python.org/3.10/c-api/typeobj.html#c.PyTypeObject.tp_alloc

Without digging in deeper and learning more I can't say for certain 
whether or not those are issues, but intuitively I assume they would be 
and that the implementation needs to more closely mirror the syntactical 
flow implementations of modern working examples..
