package pratter

expression tbl s parses stream of tokens s with table of operators tbl. It transforms a sequence of applications to a structured application tree containing infix and prefix operators. For instance, assuming that + is declared infix, it transforms 3 + 5 + 2, represented as @(@(@(@(3,+),5),+),2) (where @ is the application) into (@(+(@(+,3,5)),2).
