Hi,

This is a follow up to this thread:
https://sourceware.org/ml/gdb/2013-11/msg00101.html

Part of Doug's response there seemed to indicate that calling
overloaded operators to perform valid Python operations has not yet
been implemented. The attached patch adds this "feature". I could not
yet think of a reason as to why adding this could be bad (as in,
leading to ambiguity or something similar).

        Call overloaded operators to perform valid Python operations on
