No PEP, it's pre-PEP. The methods names are not in question, because they
mirror the current *list* method names ;) and push() is spelled 'append()'
in Python. Here's what pop() does:

>>> x = [1,2,3,4,5]      
>>> x.pop()
5
>>> x
[1, 2, 3, 4]

The question is mostly whether count(), index() and maybe remove() are worth
adding to the arrayobject, given their inefficient implementation.

(An efficient implementation would require a fair bit of code, but on the
plus side, that same code could then be used for 'sq_contains', which
currently is appallingly inefficient.)
