This paper suggests two general directions that one could take to modernize APL2 Graphpak and revitalize its evolution. One direction springboards off lessons learned during Graphpak's first decade and from some thinking that evolved during early (c. 1980) experiments with general arrays. The second direction exploits general arrays and APL2 functionality at a user-level. Some experiments are reported relating to both areas
