Yes, there are some functions which evaporated and I have never 
heard a reason why and how I am supposed to overcome their 
removal. E.g., when porting M2Crypto to Python3 I had to 
reimplement my own (bad) version of `FILE* 
PyFile_AsFile(PyObject *pyfile)` function 
(https://is.gd/tgQGDw). I think it is obvious why it is 
necessary for C bindings, and I have never found a way how to 
get the underlying FILE handle from the Python File object 
properly.   

Just my €0.02.

All of us could take a lesson from the weather. It pays no
attention to criticism.
