I want to pass a symbol table to my Menhir parser since I want to run  
several parsers in parallel and don't want any shared state.

I have this in the header of my ocamllex lexer:

   module P = EasyParser.Make
     (
       struct
         type t = EasySymtab.symtab_t
         let putsym = EasySymtab.putsym
         let infer_type = EasyCheck.infer_type
         let symtype = EasyCheck.symtype
       end
     )

rule token tab = parse
...

Above are functions that take a symbol table as their first argument  
and the lexer (token) takes the symbol table as well.

In my parser test harness I have:

let parse str =
   let lexbuf = Lexing.from_string str in
   let ast = EasyLexer.P.program (EasyLexer.token (symtab ())) lexbuf in
   List.map EasyLocStrip.strip_stmt ast

How do I ensure that the lexer and the parser use the same symbol table?

I thought I could parameterize the parser on curried functions like  
"putsym tab" but then how do I make sure that all functions in Make  
above take the same tab?

If that works than I need to ensure that EasyLexer.token in my parse  
function takes the same tab that  was used by EasyParser.Make.

Any suggestions?

	Thanks, Joel
