(author here, still getting over the first time I've seen one of my own posts on this site)

The many recommendations for J here are a great nudge for me to give it a proper go. I've taken quite a liking to the traditional APL glyphs ( see a photo of the stickers on my laptop keys in this post https://jcarroll.com.au/2023/12/10/advent-of-array-elegance/ ) so I'm not looking for a way to avoid them.

Another detraction I've seen around is about the ambivalence of APL glyphs (taking either 1 or 2 arguments and doing something different in each case). I don't particularly mind it because I think it becomes more natural to "understand" how a function is being used the more familiar you become with it, but without the limitation on the number of glyphs, I can see the benefit of separating those.
