I don't know if it that's what you are looking for, but seq.el has
`seq-let` and map.el has `map-let`, and they both use pcase.

    (seq-let (a b (c &rest others)) '(1 2 [3 4 5 6])
      (+ a b c))

    (map-let (foo bar baz) '((foo . 1) (bar . 2))
      (should (= foo 1))
      (should (= bar 2))
      (should (null baz)))
