"into: Stream" plays well with the current semantics where "into: ..."
changes the return value however, because emitting a stream would require
"for" to emit a completely different code than today, "into: Stream" would
only work if the Stream module is given at compilation time. In a nutshell,
this is welcome, but it is a relatively high amount of work.
