[Python-3000] Request for documentation: PyModuleDef

[Jan Althaus]

Please correct me if I'm wrong, but it doesn't seem like there is a  
full documentation of PyModuleDef's members available?
While some of them are intuitive, others aren't. The usage of m_size  
in particular isn't clear to me. I understand this is the size of  
additional per-interpreter storage, however I'm not sure how this  
translates to code; both in terms of declaration and functions such  
as PyModule_Create (e.g. how/when are the additional members/storage  
initialised?)
Do you reckon it would make sense to add an example for such a case  
to the Embedding and Extending part of the docs?
Ta!
