On a similar note, is there a chance we get Haskell-style infix
operators back? They allow to use a binary function add in infix
notation with backqotes: 3 `add` 4. This addition to the lexer was for a
short time in the repository, but taken out again:

    @@ -311,9 +311,6 @@ rule token = parse
                 { INFIXOP4(Lexing.lexeme lexbuf) }
       | ['*' '/' '%'] symbolchar *
                 { INFIXOP3(Lexing.lexeme lexbuf) }
    -  | "`" lowercase identchar * "`"
    -            { let s = Lexing.lexeme lexbuf in
    -              INFIXOP3(String.sub s 1 (String.length s - 2)) }
       | eof { EOF }
       | _
           { raise (Error(Illegal_character ((Lexing.lexeme lexbuf).[0]),

Are there ambiguities in the lexer?
