(a) I'm not sure I like to make that semantics official, since it's hard to implement e.g. in Jython.
Don't blame me - I told JimH he was wasting his time <wink>!
(b) I'm having another dense day. How would requiring exceptions to inherit from Exception make this easier?
Well, I implicitly hand-waved on a couple steps, like a total revamp of the sys.exc_* stuff. Bleh. No, I guess there's no way around the fact that that dangling reference is either a blessing or a curse, and which it is depends on circumstances external to the system.
(Which would allow killing off the recurrent "with" / "using" thread.)
In c.l.py? I'm not aware of it.
We just had one here. Started out on hygenic macros, but ended up on hiding finally clauses. -- Gordon http://www.mcmillan-inc.com/
