I was thinking about that. But that's really a sad thing to think of. So I
made a joke.

You were talking about introducing new types. And you're talking about
using common sense to fix the bugs. Because of the difference in common
sense of bidi users, even when they use the same language, they expect
difference things.

If we're doing an extension to the Unicode behaviour, we should try to
standardize it in an RFC or something, and we should start two separately
developed versions to test against each other.
