;;; Commentary:
;; convoluted. Instead of viper-command-argument, keymaps should bind the
;; actual commands. E.g., "dw" should be bound to a generic command
;; viper-delete that will delete things based on the value of
-;; last-command-char. This would greatly simplify the logic and the code.

;; 2. Somebody should venture to write a customization package a la
