Having just looked at the provided patch I realize that the change 
actually *is* to all layers (even though only a single backend is 
supported right now), so my earlier comment was mistaken.

OK, I agree. One additional type of expressions I would like to see is a 
compound filter involving multiple properties, such as "foo == 1 OR bar 
== 2". The current suggestion only allows expressions on a single 
property. But I agree, this is a very useful first step.

True.
