(** An pattern match on {!caml_set_oo_id args}
    Note that in the trunk, it is immutable by default now 
 *)
module E = Js_exp_make 


(* Sync up with [caml_set_oo_id] 
   Note if we inline {!Caml_exceptions.create}, 
   it seems can be useful for optimizations in theory, 
   in practice, it never happen, since the pattern match 
   never dig into it internally.
   Alternative is to create a block `["xx"]` which relies on object identity
   We try to avoid this, since inlining would break this, this would make reason
   about the correctness of inlining more difficult
