It was meant to be a bit more informative about what is wrong.

ProtocolError: lacks enter or exit

That's exactly what I'm trying to avoid. :)

I find "AttributeError: exit" just as informative. In either case, if you know what exit means, you'll know what you did wrong. And if you don't know what it means, you'll have to look it up anyway. And searching for ProtocolError doesn't do you any good -- you'll have to learn about what exit is and where it is required.
