Please do correct me if I'm wrong, but I've just recently researched APL and it seems like beyond J there really isn't anything else. There's a lot of recent research however, so maybe soon you'll see something new, but in general array based languages seem very little used and studied.

Dyalog APL has a lot of modern goodies, also J, and K.
kick 7y ago
proprietary: k7, k2/k3 (very frequently used so including them separately), dyalog APL, APL2 (still shipping), APL2000, D not proprietary: NARS, ngn/k, J, klong, aplette, gnu apl, kona javascript: ngn/apl, oK calculator (free software): ivy dead but the body's still warm (free software): xxl, nial, dead but the body's still warm (proprietary): aplx, a+ There's a bunch missing here because everyone alive has written an APL interpreter at some point (Ken Thompson did for example but it's ancient history and has a few descendents), but listing all of them would take hours. Especially if we're getting into historical stuff. They've been pretty heavily studied, though, certainly: https://vector.org.uk https://vector.org.uk (APL journal going back almost forty years) If you have access to the old IBM journal, you'll find stuff that's past fifty, the first book on it is 58, and it itself is past sixty now.

  A+ has been GPLd for 15 years or so now, and the body has been cooling since 2008 or so when the last change was made IIRC - see http://aplusdev.org http://aplusdev.org I vaguely remember it was even packaged in Ubuntu multiverse and/or Debian at some point.

    Correction now that I'm not on my phone: A+ was GPLed in jan 2001, making this 19 years ago - and indeed, the last change was in 2008 for 64-bit support, but at that point that project had been already quite stagnant for 5-6 years -- changes and releases were all concerned with documentation and newer build environments. The "electric" GUI concept (The "+" in "A+" - without the GUI it was just called "A") was much simplified in k2 - it was fast, simple and extremely effective even though it didn't really look good - it is, in fact, the only environment I've ever had a chance to use where having a GUI is as simple or simpler than writing a batch program -- see e.g. 15-Puzzle[0] or the spring simulation[1] (even though the canonical example is the S- spreadsheet which you can find at the same site).

      I mean, yeah, it's not very warm, but it, xxl and APLX are pretty much the newest dead APLs.

    I don't really see it as still alive: half of the commits in that repo in total were on that day, and only one was a change of code. Before it, the last code change was two years prior. "Mostly dead" may be more accurate, I'll grant.
