Another: see https://github.com/dlaurie/lua-apl
So 4 (at least)

Years ago I got APlus working with Xemacs (its clearly stated: not
compatible with gnu-emacs)
Then it stopped working (with xemacs that is -- some X issues?) and so
I hacked up something to make it work with gnu-emacs.
My work-in-progress page: http://www.emacswiki.org/emacs/AplInDebian

FWIW recently Xemacs is getting so bitrotten that debian has
unfortunately removed it:

This does not mean it is unavailable or uninstallable but just much harder.
Multiply that by
- APlus is also getting obsolescent
- most people (in 2013) know little/nothing about APL
and clearly the barriers to entry (on the APlus-avenue) are only increasing.

Note for a super-ace programmer (which means not me!) all these
different APLs could be supported under one umbrella in (gnu)emacs.
This entails:
1. Completing a unicode-based set of modes for Apl and inferior Apl
2. Making an latin-ish encoding for APlus
3. Having some configuation flags so that the base unicode encoding
can be converted if necessary on file-saving/process-sending
[My WIP http://www.emacswiki.org/emacs/AplInDebian basically tries to
do this but without making a new latin-ish encoding -- needless to say
it works sometimes and fails many times :-) ]

So... APL seems to be making a mini resurgence.
Anyone wanting to give a helping hand in putting emacs into the
picture will be gratefully accepted :-)
