    Description

      I would like to upgrade ANTLR from 3.5 to 4.5. This version adds several features that will improve the existing grammars. The main improvement would be the allowance of left-hand recursion in grammar rules which will reduce the number of rules significantly for expressions.

      This change will require some code refactoring to the existing expressions work.
