I'm not sure how that would be done in RDF as it stands, given its
expressive power, but it seems like a nice thing to have.

Not neccessarily. You could imagine a concrete query syntax for RDF 
  that was different to current formats. In fact I'd want syntax 
that made queries and rules fun to write - the bar should be set 
very high for usable syntax, especially for query. There's a  lot to 
be learned from efforts like the RNG compact syntax, or XPath.

If these efforts are conjoined I would still like to have specs that 
allow me to write a conformant rules engine if all I need is a rules 
engine, without having to implement  a query engine, or vice versa. 
If they're not kept apart for implementation, they become mutual 
barriers to entry.
