API question/request: Array to Stream

[Millies, Sebastian]

sorry, I misunderstood. You're suggesting to add a new varargs method to Arrays, instead of
having it in Streams, so one would write Arrays.stream(one,two) instead of Stream.of(one,two).

This would focus attention on the fact that varargs are internally treated as arrays. One could
see this as a disadvantage, I'm not sure.
