I had occasion today to look through the pa_r.ml, and noticed the
following (line 329 in OCaml 3.08.4):

  | "object"; cspo = OPT class_self_patt; cf = class_structure; "end" ->
      (* <:expr< object $opt:cspo$ $list:cf$ end >> *)
      MLast.ExObj loc cspo cf ]

So a quotation expander was created for objects as ordinary expressions,
but evidently there was something wrong with it. Anyone know what the
problem was?
