    with-memoization is a Lisp macro in ‘subr-x.el’.

    (with-memoization PLACE &rest CODE)

    Return the value of CODE and stash it in PLACE.
    If PLACE’s value is non-nil, then don’t bother evaluating CODE
    and return the value found in PLACE instead.

      Probably introduced at or before Emacs version 29.1.

It's a macro tho.
