Hi,

I'm experimenting with camlp4 and found this problem.

file: forever.ml

   #load "q_MLast.cmo";;
   #load "pa_extend.cmo";;

   open Pcaml;;

   EXTEND
     expr: LEVEL "expr1"
       [ [ "forever"; body=expr ->
              <:expr< while true do { $body$ } >> ] ];
   END;;

file: bar.ml

   let _ = forever print_string "0";

compilation:

   $ ocamlc -pp camlp4o -I +camlp4 -c forever.ml
   $ ocamlc -pp "camlp4o ./forever.cmo" bar.ml
   File "bar.ml", line 1, characters 8-33:
   Unbound value true

But when you substitute 1=1 for true this works as expected. Can true 
not be used as literal in expr quotations?

Thanks,

Maas
