> OK, I misunderstood the discussion on this ticket so far (I did not yet
look at the code carefully); I somehow concluded that your implementation
answered Simon's question from comment:13 with "yes".
I agree that it makes sense that two number fields are different if they
have a different structure. I had a feeling that this would break too much
existing code, though. I think it is a natural first step to rewrite
number fields to use a factory and make them unique parents (this ticket).
I could certainly imagine helping on a followup ticket which tries to make
`==` and `is` the same for number fields.
