Very interesting. I didn't know a GNU APL existed. Looks like it's a quite recent, from-scratch implementation mainly by one author, with its first release only a few months ago, in September 2013: http://lists.gnu.org/archive/html/info-gnu/2013-09/msg00014.html http://lists.gnu.org/archive/html/info-gnu/2013-09/msg00014.... The author, Jürgen Sauermann, doesn't seem to have a web-presence; would be curious what else he's up to, besides singlehandedly launching a new APL implementation. Is it a hobby project? Motivated by an existing APL codebase? Part of a research project? He must have quite some experience with APL, since he wrote a PhD thesis on a parallel APL system 25 years ago: http://genealogy.math.ndsu.nodak.edu/id.php?id=63307 http://genealogy.math.ndsu.nodak.edu/id.php?id=63307
