The iteration order over maps is not specified
and is not guaranteed to be the same from one iteration to the next.
If map entries that have not yet been reached are deleted during iteration,
If map entries that have not yet been reached are removed during iteration,
the corresponding iteration values will not be produced. If map entries are
inserted during iteration, the behavior is implementation-dependent, but the
iteration values for each entry will be produced at most once. If the map
is <code>nil</code>, the number of iterations is 0.
created during iteration, that entry may be produced during the iteration or
may be skipped. The choice may vary for each entry created and from one
iteration to the next.
If the map is <code>nil</code>, the number of iterations is 0.
