Anyone is of course free to fork GNU APL, or any other APLish FOSS language, and modify it to include Dyalog APL's features. However, Dyalog can only do so much amazing work because users that make significant amounts of money with Dya

It'd be nice if the code was available as Unicode text too.

⍴((U⍳U)=⍳⍴U)/U for counting the unique is wasteful too, as we only need the count, not the actual items, so +/(U⍳U)=⍳⍴U or (U⍳U)+.=⍳⍴U is enough.

As for the semantics, here are the equivalent JS functions: I = y => [...y.keys()].filter((e,i) => y[i]) // ⍸y Indices of trues in y E = (x,y) => y.map((e,i) => x.every((e,j) => e == y[i+j])

I'd be happy to teach you; just let me know. The syntax is in fact quite simple, and the semantics of the core language is mnemonic and limited, so I believe that a reasonably intelligent person can learn the entire core lanuage in 24

The syntax is actually quite simple, but you may be confused by the unfamiliar symbols and lack of syntax. 0 1 is simply [0,1] in JSON and ⍵ is the argument name. The other symbols cirrespond to prefix and infix operators. Compare the fol

Yeah, K doesn't even have proper n-dimensional arrays. Funny enough, the author writes "If you do a lot of numerical work, learn J earlier." which may be a typo, but still… > You can learn all the important parts of array

Lots of financial institutions at https://github.com/interregna/arraylanguage-companies but plenty of others too. (And that's a hobbyist-created list; not at all exhaustive.)

It absolutely does. A Torah scroll without it would be invalid for public readings.

I've often done this manually, and have wanted to automate it. Awesome!

I'm convinced a moderately intelligent person with good grasp of high school mathematics can learn the entire core of APL in 24 hours of study (which of course is more than 1 day) with appropriate tutoring. Lack of programming experien

Have you even looked into APL's syntax? It is really simple.

I just counted how many distinct symbols are in five projects I've been working on lately. They use 30–50 primitives each. Across all of them, it is 56.

Hasn't really been an issue. Occasionally, I map CapsLock to AltGr so I have a left-side APL shifting key too — it doesn't see much use, though. Also remember that it isn't "every character I type". Actual APL primi

Some tools for symbolic computations have been written in APL, but APL doesn't provide such capabilities out of the box.

If anything, you'd need B = Transpose [B] as A and B are not related.
