I meant window-swap-states, and it does use window-state-get and put.

Say you save window layout:
- +----+--+
- | A  |C |
- |____|__|
- |  B    |
- +-------+

(car (window-tree)) returns:


(t (0 0 137 30)
   ;; Following sexp is returned by (caddar (window-tree))
   (nil (0 0 137 15)
	#<window A>
	#<window C>)
   #<window B>)

In a scinario like this, where (caddar (window-tree)) is a list, the
function does not work as it will not have any anchor point.

However transpose-frame will work on the following layout, as it can
anchor of A

- +------+----+--+
- |      | B  |C |
- |  A   |____|__|
- |      |  C    |
- +------+-------+

just compiled emacs an tested it works, I'll do that
