class Foo: pass class Bar(Foo): pass Is there any argument that I can pass to Foo() to get back a Bar()? Would anyone expect there to be one? Sure, I could override new to do stupid things, but in terms of logical expectations, I'd expect that Foo(x) will return a Foo object, not a Bar object.

OSError(errno.ENOENT, "couldn't find that file") FileNotFoundError(2, "couldn't find that file")

Regards

Antoine.
