I agree on that. Only, I thought that this would be best discussed after the editorial work had been finalized, at least on a strawman basis. See my other email on that subject.

I hope so. At least, this was the idea :-)

I think that we agree that we must first converge on what semantics is useful (or even neededà and implementable for the actions. I also think that we have, now, the framework to specify that semantics in a clear, unambiguous and implementation independent way, and that, once we agree on what actions and what semantics, we can just add them in the document.

The problem I see is that we do not seem to agree on the semantics of e.g. Assert; that we do not agree on whether or not we need a Modify; etc.

I believe that we cannot progress any further before we reach an agreement on such basic questions.

Cheers,

Christian
