Make an ask for it? (Gets rejected for use map-indexed vector)

They'd probably reject asking for a :do-while as well ? So you can stop before pulling 1 more element

That can be an in house macro, there is more rationale in asking for the iter count because it could be a primitive binding

:do-while is niche, but it's likely less controversial. It has a more straightforward path to prevent taking one more than necessary. It's called :iter-count and then you bind to whatever symbol you want, I used i in my example, but I was assuming it would be the iteration count. It's true nesting is a bit more tricky, I'm guessing you could repeat it multiple times and bind different symbols so you can get the iteration count at each nesting if you want.

> repeat it multiple times and bind different symbols so you can get the iteration count at each nesting if you want On paper it sounds very interesting and I don't think there's a combination of things you could do inside for/`doseq` to achieve that. But it will also probably get countered with "what practical problem does it solve" if you were to create an Ask. :D

Ya, the use-case is that map-indexed is gnarly both in syntax verbosity and in creating intermediate sequences and vectors. Which I feel they'll likely reject

https://aphyr.com/posts/360-loopr-a-loop-reduction-macro-for-clojure can be useful for those types of use cases.

You still wouldn't be able to get the iteration count on loopr correct? You can have your own accumulator for it but it's not counting per-nesting level

I've always been grimly happy with the old "(map-indexed vector ...)" trick.

I once wrote https://github.com/nathell/clj-iter that allows for this, but haven’t felt the need for it in like 16 years (omg time flies) :)

I just find that one in the comments of the LOOPR article and was looking into it haha

lol, it https://github.com/nathell/clj-iter/blob/master/src/pl/danieljanus/iter.clj#L2`clojure.test` 😄
