#15195: Family cardinality does not catch enough errors
-----------------------------+--------------------------------------
Reporter: tscrim | Owner: tscrim
Type: defect | Status: new
Priority: major | Milestone: sage-5.12
Component: combinatorics | Keywords: Family cardinality
Merged in: | Authors: Travis Scrimshaw

-----------------------------+--------------------------------------
We have the following:
{{{
sage: C = CartesianProduct(PositiveIntegers(), [1,2,3])
sage: C.cardinality()
+Infinity
sage: F = Family(C, lambda x: x)
sage: F.cardinality()
Throws a TypeError
}}}
Fixes this by also catching type errors.
