This is a new take on an old language: APL. The goal is to pare APL down to its elegant essence. This version of APL is oriented toward scripting within a Unix-style computing environment.
If you're interested in recent developments in array languages, I recommend checking out:
ngn/k https://git.sr.ht/~ngn/k/tree/master/item/readme.txt (Previous discussion: https://news.ycombinator.com/item?id=22009241)
I'd also recommend checking out J, which isn't a recent development, but has the best syntax out of all array languages, has the best development environments, is the easiest to learn (it has a way to learn it built into the language itself!), and is the only one that treats making GUIs as a first-class feature: jsoftware.com (Has so many previous discussions I just recommend using HN search to find them.)
The chat is biased to Dyalog APL, but a lot of the modern additions Dyalog has made to the language make it (in my opinion) worse as a notation, so ideally don't let it turn you off of the concept of array languages entirely if Dyalog doesn't "click" with you.
If you haven't already, you should also check out Notation as a Tool of Thought, a paper so good it won Iverson the Turing Award:

SPOOKY EXPERIENCE: Okay, so this happened back in like 1994 when I was a kid, but I swear it happened and I'm wondering if anyone else has experienced this or something similar. Too much to type, so I will in replies.
