cell whose cdr itself is a list. The obvious way to translate this
into a widget type would be
- (define-widget 'my-list 'choice
+ (define-widget \\='my-list \\='choice
\"A list of sexps.\"
:tag \"Sexp list\"
- :args '((const nil) (cons :value (nil) sexp my-list)))
+ :args \\='((const nil) (cons :value (nil) sexp my-list)))
Here we attempt to define my-list as a choice of either the constant
nil, or a cons-cell containing a sexp and my-lisp. This will not work
Using the `lazy' widget you can overcome this problem, as in this
example:
- (define-widget 'sexp-list 'lazy
+ (define-widget \\='sexp-list \\='lazy
\"A list of sexps.\"
:tag \"Sexp list\"
- :type '(choice (const nil) (cons :value (nil) sexp sexp-list)))"
+ :type \\='(choice (const nil) (cons :value (nil) sexp sexp-list)))"

;; We don't convert :type because we want to allow recursive
;; data structures. This is slow, so we should not create speed
