> This is a result of the discussion on the mailing list. This is an excerpt from the mailing
list that gives the basic idea of the change:
> I propose to change all streaming operators to be push based, with a
> slightly improved interface: In addition to collect(), which I would
> call receiveElement() I would add receivePunctuation() and
> receiveBarrier(). The first operator in the chain would also get data
> from the outside invokable that reads from the input iterator and
> calls receiveElement() for the first operator in a chain.
