Is there a zip equivalent in core API?

[tranzystorekk]

I'm looking to zip together two data structures to solve a simple Advent of Code problem, and I got surprised when trying (seq [va :in a vb :in b] ...) ended up in nested looping instead (tbf I realize this is documented but it's still a it surprising to a rookie).

Is there some builtin way to do a zip instead? I failed to find it by looking through the Janet API docs, it all seems a bit too scattered.

Something like this?

$ janet
Janet 1.40.1-1449ad8b linux/x64/gcc - '(doc)' for help
repl:1:> (map tuple [:a :b :c] [1 2 3])
@[(:a 1) (:b 2) (:c 3)]

or may be this?

repl:2:> (zipcoll [:a :b :c] [1 2 3])
@{:a 1 :b 2 :c 3}

(map tuple a b) is what I was looking for, thank you!

Although I gotta be fair, that's really difficult to discover even when reading the docs reasonaably carefully.
