Motivation for the patch came from a tweet[1] of David Beazley:

def SomeError(Exception): 
    pass 

raise SomeError('blah')

(Note the `def` keyword instead of `class`):

If you run that, you get:

> TypeError: exceptions must derive from BaseException

Which is not very helpful.

Attached patch changes the error message to be:

> TypeError: exceptions must derive from BaseException, got NoneType

(By the way, it's very close to what Python2 used to say in this case)
