I agree they're both lost metaphors, and also that zip is really not very good. If you grok it, then sure. If you forget it, then its just a random TLA functioncall.

I'm not sure what I think zip() should be. pair() ? smooge()?

Kill ring, and the Yank buffer in Emacs are also misnamed. you don't kill things you put in the kill ring, you are doing the opposite of yank when you put things in with ^Y

Also the 'continue' statement in most programming languages does the opposite.

It does in the context of a border guard saying "continue", rather than taking you to a back room with a rubber glove.

In programming languages where it was not already taken, 'next' would have been a better choice.

transpose? In the sense that

[[1,2,3,4,5],[6,7,8,9,10]]

Becomes

[[1,6],[2,7],[3,8],[4,9],[5,10]]

Woa! Of course!

And if you use PyTorch, its O(1) operation. You just change how you index into the data.

I believe numpy introduced ndarrays with user-specified strides, that made this a O(1) operation. Even if not, it certainly predates pytorch in this regard. Pytorch (and other tensor libraries) just used the ndarray concept from numpy.

Thanks yeah I didn’t mean to imply that Pytorch invented the idea

⍉, of course.

wed()? mate()? ...or for the fanfic'ionados, ship()?

(from a comment to TFA: imbricate()?)

Or if you're working with a list of lists, the wonderful: ↓⍉↑ will do

Interleave().

Or if that's too long, int(), or leave()

> ship()?

That'd be Cartesian product.

I personally would be fine with line_up() or side_by_side().

Isn't "lining up" usually done "against a wall"?

Pair up?

Well, I've got a couple things lined up for this weekend and since I'm almost certain I will end up executing them... hmmm.

What about "glue" instead of "zip"?

(I guess that's just the same as "paste", but British English, so maybe not the best idea!)

Maybe "join" like in databases?

join already does something else

It is a join on element index, could be a default if a join field is not set?

zip makes much more sense to me. It interleaves two sequences same like two halves of a zipper interleave.

But it doesn't interleave? You get a sequence of pairs.

Touche

It’s like zipper merging in a car.

And if you don’t know how to zipper merge you really need to.
