Replying to [comment:49 ehlen]:
> @pbruin: I completely agree with the proof and this is essentially what
I tried to write in comment:30.

that my assumptions (for instance the representation of '''x''' to begin
with) are not entirely correct in every case.
OK, good to see that we agree on this. I don't think there are any hidden
assumptions that could be violated...

although the code is pretty solid now, I think.

can't hurt to double-check.
I agree. By the way, doctests still pass.
