I'm afraid this isn't a particularly good answer. Anyway I use Matlab, which I think shares some ideas with the APL-like languages. (Coders who already know they hate Matlab can skip to the paragraph labelled "Downside" below.) What's good about Matlab? Maybe the best comparison I've seen in a normal language would be LINQ in C#. If you've been writing (or reading) code that makes heavy use of LINQ, imagine re-implementing all that stuff using explicit loops with dummy indices and all the rest of that line noise. Yuck. Hard to write and worst of all hard to read. Matlab takes that further than LINQ does ... in certain directions. Basically stuff with arrays. I don't know whether the APL-likes take the same idea even further than Matlab, or just use short keywords. Downside: when your problem doesn't break down into array patterns that Matlab is good at, then Matlab stops being fun. At all. For stuff like that, where you really do need to supervise every line of C-ish code personally, something like Ruby or C# is way more fun. (Except if you're doing say EE or optical physics. Then Matlab's libraries are still a huge time saver.)
