I love both Lisp & Python. I'm not sure about large projects, but to me, nothing is easier to read than Python and a lot of people agree. It is so strict and authoritarian that nearly everyone ends up writing similar code. Good for sharing scripts on my team. If I write Perl, only I can understand it...and even that is temporary lol (I joke, but you get the point).
APL is a real programming language used in specialized domains like finance since the 70's I believe and can convey a lot of information in a single line of code. It looks like Greek symbols because it was developed by a mathematician. Pretty cool stuff. The primitive data type is the array so it works well with parallel calculations...etc.
Agreed, it is just a toy, but the parent level comments mainly seem to say that they find both this and emojis to be a step in the wrong direction. I seriously doubt they think people playing in this mini-language will bring about an Orwellian dystopia.
