C++ method call for a gdb.Value object from within python

[qq qq]

http://sourceware.org/gdb/onlinedocs/gdb/Values-From-Inferior.html#Values-From-Inferior
has an example that shows if a gdb.Value object is of type TYPE_CODE_FUNC, we can make the function call from within python.

If a gdb.Value object is of type TYPE_CODE_METHOD, how do we make the call from within python?

Thanks.
