You could just call gdb.Function.__init__(self) explicitly rather than the syntactic sugar of super(). But does subclassing work at all? I had the impression that many gdb classes don't allow subclassing. Or it might not be rejected but it may not work. I haven't looked at how to make a class in C that can be subclassed; my impression is that it definitely takes work and I don't know if the necessary magic has been implemented.
For example, method calls in subclassable classes have to be via attribute lookups and Python calls, they can't be direct calls. Ditto data attribute references.
