No, here i do not agree with you and Stephen. Reasons: - Changing current `window-list' so it always returns a somehow canonical ordered list is very simple and has really no disadvantage (at least as fas i can see) - A window list is not only for walking through the windows of this list (for this task `walk-windows' is indeed the right and better function. But sometimes i want to get the current-window-list of a frame, save it and use it later (maybe comparison or something else). I think you can not progose for which jobs a programmer could use the result of `window-list' and maybe some of these jobs could profite from the fact that the ordering of the result list is known. Currently it is undefined (i mean the order of the list is always the same but the docu does not say anything about the order!) - Just that i can rely, that `other-window', `next-window', walk-windows' and `window-list' always operate/return (on) the windows in the same order is IMHO a valuable fact even it is just for consistency. I really not understand, why my suggestion to make `window-list' returning a defined order (and then why not using the "canonical" order of some other window-functions?!) runs against you, because the change is very simple and has really no side-effects for existing code (because existing code is not allowed to be based on any order of the result list, because there is no defined order like Stephen says right) and also has no other disadvantages (or can you tell me any?).
