Yes, I agree that retrieving the locals with PyEval_GetLocals and then
sticking something in there on the C side is weird. I wouldn't say that
the Python compiler is not aware of it though (I could ask my question
purely in Python: how do I check in the scope of fun2 whether 'q' is
available in the outer scope without actually using it).
> I wonder, would a 'nonlocal q' declaration inside fun2 affect things
Yes, that pulls in 'q', but I would like to do that 'nonlocal q' on the
C side. If I have to write 'nonlocal q' inside fun2 then I can also
pull in 'q' using any other reference to 'q'.

There might very well be...
