I'll try to work something out today. I agree that if we do can have
something similar, let's have it.

However, as anthony poses it, we'll differ _somewhere_, and the whole
question is where to hook.
In a level lower than that, we can probably share more code, true, but
we'll end up with an API
that means a lot less, and much more difficult to get right.

The idea of sharing I have in mind right now is close to what I did
wrt to io handling.
