That is, `viper-vi-basic-minor-mode' is before `view-mode' in

are highly inconsistent and appear random.
That is disturbing. But I just came across this in the Active Keymaps
node of the Emacs Lisp manual:
| Normally the active keymaps are the `keymap' property keymap, the
| keymaps of any enabled minor modes, the current buffer's local keymap,
| and the global keymap, in that order. Therefore, Emacs searches for
| each input key sequence in all these keymaps. Here is a pseudo-Lisp
| description of how this process works:
|
| (or (if overriding-terminal-local-map
| (FIND-IN overriding-terminal-local-map)
| (if overriding-local-map
| (FIND-IN overriding-local-map)
| (or (FIND-IN (get-text-property (point) 'keymap))
| (FIND-IN-ANY emulation-mode-map-alists)
| (FIND-IN-ANY minor-mode-overriding-map-alist)
| (FIND-IN-ANY minor-mode-map-alist)
| (if (get-text-property (point) 'local-map))
| (FIND-IN (get-text-property (point) 'local-map))
| (FIND-IN (current-local-map))))))
| (FIND-IN (current-global-map)))
|
| Here, the pseudo-function FIND-IN means to look up the key sequence in
| a single map, and FIND-IN-ANY means to search the appropriate keymaps
| from an alist. (Searching a single keymap for a binding is called "key
| lookup"; see *Note Key Lookup::.)
Does `C-h v overriding-local-map', `C-h v emulation-mode-map-alists', or
`C-h v minor-mode-overriding-map-alist' explain the behavior you see?
