I'm very nervous about this.

Firstly as I commented before I can't imagine at present what a
declarative spec would look like, although I'm quite willing to believe
that is just lack of imagination on my part, but that makes it hard to
say whether I think it would be good or bad thing to have.

But more worryingly, even if the more declarative style is viable,
having two means that either they are easily seen to be equivalent, in
which case it's not clear if you gain by having both. Or they are not
easily seen to be equivalent, in which case there is a real possibility
that they are different and perhaps incompatible, that surely would be a
problem?
