I've not grokked Rails yet, but yes, it is Domain Specific. The
problem is not designing the language (because I know the sort of
things I want to say); the problem is how to parse it with some

it.  Also I don't want to open up security holes unneccesarily:
"Deliver us from Eval". One doesn't intend to get hostile users, but
the possibilty is there.
