For what it is worth, I found the discussion I was remembering: http://bugs.python.org/issue7796 And as someone pointed out down thread, the actual check is "inherits from tuple and has a _fields attribute". That gets you a duck type, which is generally what you want in Python.
I think it's a bit complicated (and not obviously discoverable) as far as duck-typing goes.
