The first NARS (Nested Arrays Research System) was designed and implemented in the early 1980s as a testbed for new ideas in APL, principally with nested arrays. A quarter of a century later, it's time to try again.
The goal of this effort, as with the last one, is to foster new ideas about the language and its implementation.
Language ideas include new functions, operators, and datatypes. To aid in getting your ideas into an implementation, there will be a mechanism for telling NARS that a user-defined APL function represents a new primitive function, operator, or datatype. In order to experiment with your ideas for new extensions, all you need to know is how to write APL programs.
