[Feature Request] racket/vector does not have a index-of

[jestarray]

(define (vector-index-of v p?)
  (for/first ([x (in-vector v)]
              [i (in-naturals)]
              #:when (p? x))
    i))
(vector-index-of #(1 3 5 8 9) even?) ; returns 3

There is index-of for lists but it does not work on a vector. I suggest adding one for vector!

Seems more like index-where instead of index-of?

[jestarray]

ohh yeah, index-where is what i meant.

Would a version that worked on arbitrary sequences instead of just vectors work for you?
