Subject: Anonymous classes
Could we have anonymous classes, as a natural counterpart to
anonymous functions?
let x =
object
method foo = 17
end
in
...
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__ =
struct
class c () = object $cspo$ $list:cf$ end ;
end
in
new Dummy__.c () >> ] ] ;
(except that the definitions of class_structure and class_self_patt
need to be copied from pa_o.ml)
