To pull on that string some more. I think we should move the implementations of
various Binding::verify methods here, or perhaps into a separate
BindingVerifier class.
Ditto for the Binding::interpret implementations. They could be moved to
BindingInterpreter. The Binding class would just be left as a simple bag of
records + documentation for each operator.
The main motivation for this would be that, if you're looking at e.g.
interpretation in `Binding`, there's a lot of noise that you have to filter
through. I think it makes more sense to group these things into classes (for
specialization/verification/interpretation), where all the code in a class is
logically related.
