Now that Iʼve actually run some more tests, I see where the confusion
is coming from. You canʼt actually eval this:

    (defvar-keymap winner-repeat-map
      :doc "Keymap to repeat winner key sequences.  Used in `repeat-mode'."
      [left] #'winner-undo
      [right] #'winner-redo)

or this:

    (defvar-keymap winner-repeat-map
      :doc "Keymap to repeat winner key sequences.  Used in `repeat-mode'."
      <left> #'winner-undo
      <right> #'winner-redo)

(but you can stick them in a .el file)

But you can eval this:

    (defvar-keymap winner-repeat-map
      :doc "Keymap to repeat winner key sequences.  Used in `repeat-mode'."
      "<left>" #'winner-undo
      "<right>" #'winner-redo)

Well, TIL. I donʼt think itʼs going to result in any patches from me
though, unless we want to disallow `[left]' and `[right]' in
`defvar-keymap' :-)
