collection VS Iter

It's a transposition, did it in PHP here: https://github.com/loophp/collection/blob/master/src/Operation/Transpose.php

I didn't know that one, but I might definitely implement it in https://github.com/loophp/collection tomorrow!

I'm working on it, I hope I can release it before the end of the year. There is a last pull-request which is preventing me from moving forward: https://github.com/loophp/collection/pull/270

Thanks for your super article. I might add a link to it in https://github.com/loophp/collection

I personally would like to see them removed and replaced with their equivalent that would work with iterables. This is the reason why I wrote this : https://github.com/loophp/collection

Or https://github.com/loophp/collection completely lazy.

I'm using that all over the place in here : https://github.com/loophp/collection/tree/master/src/Operation

I much prefer the https://github.com/nikic/iter approach for doing some collection magic, which is essentially based upon traversable and generator magic which doesn't create temporary in-memory data structures but works on item streams instead.

What about https://github.com/nikic/iter ?

Yes. We used it heavily when processing large amounts of data from huge API responses. I like how the whole processing chain can be built on top of it, for example using nikic/iter. Generators are also the heart of a low-memory JSON parsing library halaxa/json-machine, which I maintain, and many other similar projects.
