Could a widget for command functions perhaps be added to Emacs?
(defvar widget-command-prompt-value-history nil
"History of input to `widget-function-prompt-value'.")
(define-widget 'command 'restricted-sexp
"A command function."
:complete-function (lambda ()
(interactive)
(lisp-complete-symbol 'commandp))
:prompt-value 'widget-field-prompt-value
:prompt-internal 'widget-symbol-prompt-internal
:prompt-match 'commandp
:prompt-history 'widget-command-prompt-value-history
:action 'widget-field-action
:match-alternatives '(commandp)
:validate (lambda (widget)
(unless (commandp (widget-value widget))
(widget-put widget :error (format "Invalid command: %S"
(widget-value widget)))
widget))
:value 'ignore
:tag "Command")

I think the original implementation (where the widget `command'
inherited from `function') was much better. But I know no reason
why it is not in wid-edit.el now :( You can find it here:

Ok ;-)
Anyone of them would do. Should I send my widget for major modes now, or?
