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
