> The RandomValues class returns references to its internal buffer as random
> values. This buffer gets a random value every time a new random value is
> requested, but since earlier values reference the same internal buffer, they
> get changed to the same value as well. So even if successive calls return
> different values each time, the actual list of these values will always
> consist of a single value repeated multiple times. For example:
> ||n-th call||returned value||accumulated list expected||accumulated list
> actual||
> |1|6C|6C|6C|
> |2|8F|6C 8F|8F 8F|
> |3|52|6C 8F 52|52 52 52|
> |4|B8|6C 8F 52 B8|B8 B8 B8 B8|
