The difference between using and mentioning is fairly philosophical. 

As far as I'm concerned <:expr < 3 + 4 >> is simply a syntactic short hand 
for something like AstPlus(AstConstInt 3, AstConstInt 4). That fact that 
these constructors in some way refer to another thing is not particularly 

My point about functions was that you seemed to be defining "using" as 
executing, which is obviously only possible for a quotation that represents 
OCaml functions.
