Me too. And it would be a good idea, I think, to specify explicitly in the
dir() docs this behavior. Right now at least rlcompleter and ipython's
completer can break due to this, there may be other tools out there with
If it's a stated design goal that dir() can return non-strings, that's fine. I
can filter them out in my completion code. I'd just like to know what the
official stance on dir()'s return values is.
