@defun delete-dups list
This function destructively removes all @code{equal} duplicates from
@var{list} and returns the result. Of several @code{equal}
occurrences of an element in @var{list}, @code{delete-dups} keeps the
last one.
The value of @var{list} after a call to this function is undefined.
Usually, we store the return value back in @var{list}:
@example
(setq list (delete-dups list))
@end example
@var{list}, stores the result in @var{list} and returns it. Of
several @code{equal} occurrences of an element in @var{list},
@code{delete-dups} keeps the first one.
@end defun
