Streams represent physical resource exposed by OS, so they are not copyable.
What that would mean anyway.
However, streams can be implemented as shared handlers or wrapped with shared
handlers and those handlers can be copyable of course.
But still, copies would refer to the original resource.

It's unclear to me what it means to create new stream.
Is it new stream to existing resource or new stream together with new resource?
