Review Comment:
I hope I made the change you wanted. It already mentioned returning a
RexCall, but didn't mention anything about getting it from the
FunctionRegistry. Although I want to be careful not explicitly mentioned
FunctionRegistry because this is an interface and can be theoretically
overridden by a third party implementation.
