Walks into the APL design space

Abstract

Like any living language, APL is evolving. The design space for its future development is wide open. Some trails into that space are known, for other languages have followed them. We will walk on some trails, visit some sights and also some dead ends. We will see which development areas could solve some old problems of APL, without changing its fabric. The goal of the paper is to enable the reader to explore the APL design space on his or her own. To that end I will point the reader to some good books and articles about problems and solutions only touched upon in the paper.
