Thanks for writing it up. I've thought about dataflow programming before but building the dependency graph up was always annoying and the idea of sticking everything in a map and building the dep chains by introspecting the argument names hadn't occurred to me. With the ease of use solved this is handy enough that I'll probably turn it into a real promise-based utility.
Awesome, I'm excited to see what you come up with. If you do end up making something, please email me a link (I wrote you earlier) since I'm sure there's lots to be improved in our implementation.
