Dyalog APL, along with other modern array languages that are related to it can all do imperative programming with loops etc. There are certainly valid arguments that you hive certa…

Thanks, that makes sense. I guess most CSV data you see in the real world do have headers. Perhaps I was looking too much about thr default CSV export format from Excel, focusing o…

I see. Kap tries to be as generic as possible, so assuming that the table has headers doesn't feel right. If the table dont have headers, and the reader assumes it does, then you'l…

The string to specify the column types is not a terrible idea. Does it have other configuration options, like whether or not to assume the first row is the headers, or specifying t…

That wouldn't help much. People who don't use these languages doesn't understand that what makes the language different isn't the syntax. There are plenty of dialects that use Engl…

Which would have been fine. In fact, if you read the notes from the very first implementation of APL you'll find that it was noted that they considered the lack of proper flow cont…

That list is incomplete. Those are things that Lisp invented but is now commonplace. What it also invented but rather few languages also support is the capability of metaprogrammin…

This is a good article to understand the thinking behind array languages in general, and APL in particular. However, I disagree with some points made. In particular, this one: > So…

To be fair, most languages in use today are just FORTRAN with diffrent syntax. Both Lisp and array language programmers are sadly somewhat rare.

Interesting observation. The fundamental syntax of Kap is the same as APL. The imperative style is added on top, and isn't really the way you'd normally write code. The examples we…

That depends on the specific code. Some code is written to be agnostic to the rank, while others make certain assumptions. In my code I'd sometimes write assertions in the beginnin…

Just because you can write everything on one line without any spaces doesn't mean you should. You can ofcourse removethe capability to do thatand you'll effectively force the progr…

It's likely a combination of both. It's certainly possible to write Kap in a much more condensed form. But things like if-statements and hash maps does allow for a more imperative …

You're not wrong. It's very easy to get that impression when trying to learn the array languages. It's very easy for someone who's used these languages for a long time to look at a…

"More efficiently"? Maybe. It opens up a new way to think about solutions to problems. Sometimes those solutions are more efficient, and sometimes they are just different. It's a u…

The short answer is yes. There have been many presentations on this topic that tries to explain it in various ways. The problem is that most people who are unfamiliar with APL usua…

It's not sort. In Kap, sort down is ∨. The grade functions returns a sorted index. Basically ⍒ 3 1 2 1 1 returns 0 2 1 3 4. So yes, it performs a sort, but it returns an index that…

I am the author by the way. The intent wasn't really to try to sell the language. The language is what it is, but the thing I wanted to highlight was that the entire solution (lang…

Well, it's for the JVM, JS or Linux native. :-) Point taken about the tutorials. It's still a work in progress.

That was not the point of the statement. The argument (possibly poorly phrased) was the there are people people out there that are comfortable with manipulating arrays of numbers t…

I'd argue it's partly because of tradition. If you look at early APL code, including Iverson's earliest papers, it's written with pretty much zero spaces (well, except for where sp…
