* for TypeError, which can conditionally exist.
*
* Next, Exception is created since it is the common subclass for the rest of
* the needed exceptions for this bootstrapping to work. StandardError is
* created (which is quite simple) followed by
* TypeError, because the instantiation of other exceptions can potentially
* throw a TypeError. Once these exceptions are created, all the others
* can be created in any order. See the static exctable below for the
* explicit bootstrap order.
*
* All classes after BaseException can be created using PyErr_NewException().
