Now we are talking!

This is

module Make (Lexer : Sig.Lexer)
: Sig.Grammar.Static with module Loc = Lexer.Loc
                       and module Token = Lexer.Token
= struct

   module Structure = Structure.Make Lexer;
   module Delete = Delete.Make Structure;
   module Insert = Insert.Make Structure;
   module Fold = Fold.Make Structure;
   include Structure;
   value get_filter () = gram.gfilter;
   value extend = Insert.extend;

I read the documentation for 'include' but couldn't quite grasp  
whether the included interface was exported from that module that's  
including. Given that 'get_filter' is available but 'using', I reckon  
the answer is NO.

What if Static1 included Static after making it, then included  
Structure again and defined its own using in terms of the one provided  
by Structure?
