- * assumptions about the existence of any other exception class -- except
- * 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().
