That may be true once the query is parsed. I'm not sure
as I am out of my depth.  I do know that "Select instances From classes where 
instance.foo()=bar" is a site easier for most developers(or end-users) to use 
as it resembles something they already know.  For my purposes, I would
rather take to performance hit and have a less steep learning curve.

Again, just my two cents.
