There are many reasons to do tuple access explicitly, and actually few
reasons to have PyArg_ParseTuple to do it for you.

You might want to do it explicitly if:
- you don't know the total number of elements in the tuple in advance.
- you are willing to accept not just tuples, but arbitrary sequences,
  for better polymorphism.
