No, I don't see that as particularly the issue. What I'm concerned
about is the prospect of different parts of the same opfamily being
represented in different notations --- that sounds pretty error-prone
to me. Greg is arguing that special-casing some minimum subset of the
opclasses is a good idea, but I disagree. I think if we can make the
idea work at all, we can migrate *all* the built-in opclasses into the
higher-level notation, and that's how I want to approach it.
