Not really related but the PEP says that arguments in Python are evaluated
before the function (as a reason to reject the idea of None-aware function
call) but this is not the case:
>>> import dis
>>> dis.dis(lambda : f()(g()))
1 0 LOAD_GLOBAL 0 (f)
3 CALL_FUNCTION 0
6 LOAD_GLOBAL 1 (g)
9 CALL_FUNCTION 0
12 CALL_FUNCTION 1
15 RETURN_VALUE
