Just throwing a bit of related thoughts that came and go up w.r.t. 
output ranges.

We really should add multiplexer (one sink writes to many) and 
demultiplexer adapters (by applying n-ary predicate and putting the 
result into a single sink).

And a 3rd filter primitive, as a wrapper of a sink that applies some 
predicate before forwarding it down the line.

Together with other suggestions would make output ranges *much* more 
powerful/useful.
