I don't like that answer. I can think of legitimate
reasons for wanting to pre-create exceptions, e.g. if
I'm intending to raise and catch a particular exception
frequently and I don't want the overhead of creating
a new instance each time.

For me, this is casting serious doubt on the whole
idea of attaching the traceback to the exception.
