Fascinating! What about: except sys.intern('type error') ? Or does
interning of strings not exist yet :)
Even if it was, I don't think there was any guarantee
that the "official" strings representing those exceptions
would be interned.
You were supposed to use the provided names to refer to
built-in exceptions, to make sure you were referring to the
same object.
Doing so also had the nice benefit that when exceptions
became classes, most existing exception-handling code
continued to work unchanged. It's almost like Guido had
a time machine!
