(***
 To maintain top level interface we simulate old primitve
 call_sym in terms of new primitive call_sym_and_convert.
 This signature adds call_sym to LowerLevelSig.

signature OrigLowerLevelSig =

    (*local open Ctype
    in*)
    val call_sym     : sym -> (Ctype.Ctype * vol) list -> Ctype.Ctype -> vol
