Hi,
Consider the following two programs:
----------------------------------------------------------
$ cat junk.ml
let _=fun x ->
match x with
| <:str_item< $exp:e$ >> -> ()
| _ -> ()
;;
$ camlp4of ./junk.ml
fun x ->
match x with
| Ast.StSem (_, (Ast.StExp (_, e)), (Ast.StNil _)) -> ()
| _ -> ()
----------------------------------------------------------
and
----------------------------------------------------------
$ cat junk_r.ml
value _=fun x ->
match x with
[ <:str_item< $exp:e$ >> -> ()
| _ -> ()]
;
$ camlp4rf ./junk_r.ml
let _ x = match x with | Ast.StExp (_, e) -> () | _ -> ()
----------------------------------------------------------
Why does the second program expand to Ast.StExp while the first expands to Ast.StSem? I would like, and expect, the first case to expand to Ast.StExp and not Ast.StSem.
