It makes Cython treat BaseException as an extension type
(Exception is declared similarly) and allows for things like:
* Using "Exception" as a type for parameters, attributes, casts.
All this with Cython-generated and optimized typeckecking.
* Creating Exception subclasses as cdef classes.
It's a hack, but a very useful one.
