emacs/test/lisp/emacs-lisp/cl-extra-tests.el
Tino Calancha 4daca38d5c Prevent for consing in cl-mapc and cl-mapl
* lisp/emacs-lisp/cl-extra.el (cl--mapcar-many): Add optional arg ACC;
If non-nil, accumulate values in the result (Bug#25826).
(cl-mapc): Do computations inside function instead of call cl-map.
(cl-mapl): Do computations inside function instead of call cl-maplist.
* lisp/emacs-lisp/cl-lib.el (mapcar): Add autoload cookie.
Call cl--mapcar-many with non-nil 3rd argument.
* test/lisp/emacs-lisp/cl-extra-tests.el (cl-extra-test-map)
(cl-extra-test-mapc, cl-extra-test-mapcar, cl-extra-test-mapl)
(cl-extra-test-maplist): New tests.
