This sounds like more work than is truly necessary. There is really only
one good reason to specify a grammar when defining a domain, and that is
to disable troublesome operator overloads. My suggestion would be to not
specify your dsel's grammar up front, but rather only validate full
expressions at the point of evaluation. You lose no safety that way.
