buildExprParser :: forall m s a. OperatorTable m s a -> ParserT s m a -> ParserT s m a

buildExprParser [ [ Infix (string "/" $> div) AssocRight ]
                , [ Infix (string "*" $> mul) AssocRight ]
                , [ Infix (string "-" $> sub) AssocRight ]
                , [ Infix (string "+" $> add) AssocRight ]
                ] digit
