Thanks! Did take a look at mpipe (its actually referenced in the readme). But mpipe has its flaws:

1. It uses None as the stage terminator, this is VERY error prone, what if you actually want to send None? Pypeline uses a special private terminator.

2. You have to first manually put all the data into the pipe in a for-loop and then manually get it out. In Pypeline all this is simplified: it consumes iterables and all stages are iterables, so its 100% compatible with any function/framework that accepts iterables.
