Non-heap types, aka builtin types, cannot have their attributes changed by Python code -- see Objects/typeobject.c: type_setattro(). This limitation is good for Python's core builtin types (int, float, list, dict, ...), but not necessarily for non-heap types in extension modules. The attached patch allows for non-heap types to mutate iff the Py_TPFLAGS_MUTABLE_BUILTIN flag is set.
