Huh? What makes you believe that?
I'm talking of 2.3, of course.

Sure, it is possible for long-running functions to wrap
any exception-raising stuff into an extra wrapping function
that always returns after the exception has happened,
and to let the main worker function run without try..except.
But is this very cool?

I would also like to point out that the documentation
of sys.exc_info is very misleading, and I always
programmed acording to this false information:

"""
 >>> print sys.exc_info.__doc__
exc_info() -> (type, value, traceback)

Return information about the exception that is currently being handled.
This should be called from inside an except clause only.
 >>>
"""

Where I have to say that I'm in favor of doing like
the documentation claims.
