Ok, so thanks everyone for the helpful hints. That *was* a typo on my part (should've been super(B...) not super(A..), but I digress)
I'm building a public API. Along with the API I have a few custom types that I'm expecting API users to extend, if they need too. If I don't use name mangling, isn't that considered bad practice (read not defensive programming) to not protect those 'private' fields? -- http://mail.python.org/mailman/listinfo/python-list
