   Could we have anonymous classes, as a natural counterpart to
anonymous functions?

        let x =
            method foo = 17

They would sometimes be useful for specifying the little bits of `glue'
one needs to interface a library routine with one's current problem.

   On the other hand maybe this kind of sugar isn't strictly
necessary, since I found this pretty easy to add with camlp4 :-),
using a dummy local module.

        expr: LEVEL "simple"
          [ [ "object"; cspo = OPT class_self_patt;
                        cf = class_structure; "end" ->
                <:expr< let module Dummy__ =
                            class c () = object $cspo$ $list:cf$ end ;
                         new Dummy__.c () >> ] ] ;

(except that the definitions of class_structure and class_self_patt
need to be copied from
