Sorry. Itchy trigger finger and tired brain. I didn't read the whole context of the thread. Dunno what it's doing here. Forcing __repr__ to be called on a print statement? Funny way to do that. Like I said, I don't know, so I'll leave it to someone else to say. Cheers, Cliff -- http://mail.python.org/mailman/listinfo/python-list
