Hi Henry,
I find the the cast to Spliterator<T> in Streams.concat() dubious,
I can not see how it can be correct, could you explain why this cast
is Ok.
cheers,

Hi,
I think that if we want to concat say Stream<Integer> with Stream<Long>,
producing Stream<Number>, there would have to be an unsafe cast
somewhere. Since Stream<T> API apears to be covariant (like for example
Iterator<T>), casting Stream<? extends T> to Stream<T> seems to be safe.
