Well, I'm usually going backwards when I pull :-)

Is "forward-only" in contrast to "forward-and-backward""?  If so, why
would stuff have to flow backward?

Sounds like there's an I/O layer between each component, otherwise I can't
make sense of it.

Isn't the problem with "pulling", as opposed to "being pushed", that the
puller now would have to farm out work based on examining the input?  No
polymorphic dispatch because the switch statement block is "small"?
