I too am eagerly awaiting a good tutorial on Camlp4. I've done a few things using Camlp4, and for me the syntax seems to be needlessly obscure. For example, here's how to write an infix 'map_with' operator, the syntax being: 'list map_with f' which is equivalent to 'List.map f list': open Pcaml EXTEND expr: AFTER "apply" [ LEFTA [ e1 = expr; "map_with"; e2 = expr -> <:expr< List.map $e2$ $e1$ >> ] ]; END Rich. -- Richard Jones, CTO Merjis Ltd.
