actually come to think of it isn't c's || strictly boolean too
as in it takes ints and outputs either 0 or 1 as an int

Is there a challenge to do this:
[5]
[0, 1, 2, 3, 4]
[0, 0, 1, 0, 1, 2, 0, 1, 2, 3]
[0, 0, 0, 1, 0, 0, 1, 0, 1, 2]
[0, 0, 0, 0, 1]
[0]
[]
Essentially, repeatedly replace n with range(n) and flatten until you get an empty list, or something similar
 
caird coinheringaahing

I think we've had that but with 1 indexed ranges?
But also, what's the challenge? Output the steps?

See, say what you will about Jelly, at least the builtins kinda make sense :P
ḶF$Ƭ - (lowered range, flatten)$ Til
I can kinda guess that ʁ is range from 0, and f is flatten, but I'm not even sure that's correct

Pretty much - next two as a lambda or group next two together (depending on whether it's in a modifier
Vyxal's range builtins are r for dyadic pythonesque range, ʀʁɽɾ for various types of range(0 or 1, a or a+1), ṡ for inclusive range, Ḣ for range(2, a+1)... do we have enough?

the ranges from zero are uvular because they're further back, and the approximants only approximately reach the input

i feel like there are a few more rangifying builtins than that but i guess they don't really count when the output isn't recognizably a range :P
really there are only four range builtins + three simple list builtins that happen to rangify
 
caird coinheringaahing
caird coinheringaahing
There's also things like prime range :P
@UnrelatedString Personally, I classify Ż as more of a range builtin, with a useful list option

@UnrelatedString Huh, I'm the opposite. I use it for zero range more

CMP: what's a good width height ratio for monospace fonts?
in my brain theyre some sort of rough 1:2 but upon actually testing i realized that ratio is a bit thin...

yeah definitely more in the ballpark of like 4:7
take the cjk pill and go 1:1
