(I haven't seen this mentioned yet.)

You don't see new array-oriented languages often. In fact I can only think of a handful that have ever been created, the most well-known being Iverson's APL and it's successor, J. Now there's Glee. It's still under development, but the author posts frequent updates to his already voluminous web site.

Unfortunately, it's only for Windows, and apparently it's only runnable if you have a specific *compiler* on Windows (!).

I just had a quick look.

Are Array Processing Languages doomed to be unreadable?

(Full disclosure: I am a big fan of J and APL )

I like ZPL's notion of regions and directions. For example (from the walk-through), after declaring

region     R       = [1..n, 1..n];
direction  north   = [-1, 0]; south = [ 1, 0];
           east    = [ 0, 1]; west  = [ 0,-1];

you could write things like

[R] Temp := (A@north+A@east+A@west+A@south) / 4.0;

where the prefix [R] limits the region that operation applies to.

Nial ( is the most readable array language I've seen, but it seems to be a defunct commercial effort. And I have to admit that I really get into the J notation, when I find the time to soak in it, but I forget it very quickly.
