Hi,

Is there something like

| (defun filter-list (pred list)
|   "Make a list of all LIST elements satisfying PRED."
|   (let ((deleted '#:deleted))
|     (delete deleted
|             (mapcar (lambda (el) (if (funcall pred el) el deleted))
|                     list))))

existing in Emacs Lisp?  I can't find it, but I would expect such
an elementary function would be built in.  Do I miss something?


Thanks,

Michael.
