I see weird symbols like that I think APL. I haven't touched APL but I know weird symbols when I see it.

And checking the article... Tags: apl

Aren't those the Twin Pines from Back to the Future?

Did you mean the Lone Pine?

an obscure but very powerful matrix-centered programming language usually considered to be "write only", as in impossible to read what someone else wrote.

Can you even read what you wrote several years ago?

Wait, isn't that what they say about perl?

Yes, perl is considered write-only because it is a mess of features that allow unhygienic programming habits to flourish - it is full of hard-to-trace magical behavior. Completely different than APL, which has had perl's write-only label applied to it by programmers not used to reading terse mathematical notation.

They say the same about RegEx too.

40 years ago (at school) I generally wrote in ink - edged and straight nibs, blue and black ink because I liked it. I learned several formal styles as well as my idiosyncratic efforts. I did have biros and fibre tips etc available. I had loads of choice. My parent's generation was probably the last of the ink and nib first users.

Very much not.

Its origin is as a mathematical notation for algorithms. It was used to publish research reports and (IIRC) a book or two.

You're confusing "possible to read" with "accessible to people unwilling to invest any effort understanding"

Only by the ignorant and uninitiated.

"a programming language".

Not to be confused with b programming language, which is not its succesor, but is the predecessor to c.
