REMOVED EFUN
SYNOPSIS
        mixed *map_array(mixed *arr, string fun, string|object ob, mixed extra)
        mixed *map_array(mixed *arr, closure cl, mixed extra)

DESCRIPTION
        Returns an array holding the items of arr mapped through
        ob->fun(element, extra) resp. the closure cl. The function fun
        in ob is called for each element in arr with that element as
        parameter. A second parameter extra is sent in each call if
        given. ob can be an object or a string. Principal function:

        foreach (index) arr[index] = ob->fun(arr[index],extra);

        The value returned by ob->fun(array[index],extra) replaces the
        existing element in the array. If arr is not an array, then 0
        will be returned.

        The extra argument is optional and must not be a protected reference
        like &(i[0]). If <ob> is omitted, or neither a string nor an object,
        it defaults to this_object().


EXAMPLE
        string ask_for_uid(object obj) {
           return getuid(obj);
        }

        void func() {
           string *names;
           names = map_array(users(), "ask_for_uid", this_object());
           /* equivalent but a bit smaller and faster is the following */
           names = map_array(users(), #'getuid );
           ...
        }

        This will create an array holding all uids of the current
        users.

HISTORY
        Since LDMud 3.2.6 obsoleted by map().
        Since LDMud 3.2.9, not available if driver is compiled without
          USE_DEPRECATED.
        Removed in LDMud 3.3.
