Caveat: I don't actually use codecs much, so I don't know the specifics. I'd be quite happy with importing having a side-effect here. If you import a module that implements a numeric type, it should immediately register itself with the Numeric ABC, right? This is IMO equivalent to that. > As far as I know, there is no way to find out what error handlers are > registered, and no way to deregister one after it has been registered. The only risk that I see is of an accidental collision. Having a codec registered that you don't use can't hurt (afaik). Is there any mechanism for detecting a name collision? If not, I wouldn't worry about it. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
