"""
pointerprimitivetype_test.py

check that the primitive types are correctly mapped by the signature module.

Mapping
-------
IntArray2(const int*)                 --  <Signature (self, data: typing.Sequence)>
getMargins(int*,int*,int*,int*)const  --  <Signature (self) -> typing.Tuple[int, int, int, int]>

We explicitly check only against typing.Iterable in the first test,
because typing.Sequence is a subclass, but we will generalize this
to typing.Iterable in the future.
