The proposal says that syntax objects are opaque and that syntax forms
evaluate to syntax objects.  The formal description may need to be even

It's not needed, since it's easily defined using syntax-case, but perhaps
we should include it anyway.

I've made a note of this.

Thanks for your comments.
