That's the notation currently proposed for Dataflow.  I would prefer no 
operator overloading here, but would accept operator|.  Stjepan, is 
there any precedent (other languages etc.) for >>=?

Hmm, but we can (in principle) stack both input iterator adaptors and 
output iterator adaptors, can't we?  Doesn't that give us both pull and push?

And there are also streams, and we have adaptors that convert streams 
into iterators (and vice-versa?).  Is there some common ground (i.e. 
some shared concepts, or shared notation or vocabulary) here?
