I agree the distinction is pedantic. It does matter sometimes, such as:
if a C++ constructor raises an exception, will the corresponding destructor
be run, or not? (No, because it never finished making an object of type T.)

But in any case, all the more reason not to let C++ semantics govern
Python vocabulary.
