val ctyp : MLast.ctyp Grammar.Entry.e;;
val let_binding : (MLast.patt * MLast.expr) Grammar.Entry.e;;

Some grammar and entries of the language, set by pa_o.cmo and pa_r.cmo.

type 'a printer_t = ('a -> unit) ref;;
val print_interf : (MLast.sig_item * MLast.loc) list printer_t;;
val print_implem : (MLast.str_item * MLast.loc) list printer_t;;

val input_file : string ref;;

The file currently being parsed.

val output_file : string option ref;;

The output file, stdout if None (default)

val report_error : exn -> unit;;
