#3Nicely done, thanks! Still, having to explain a concept as simple as eventual computation reinforces my belief that promises as a whole is broken, and should be done in something that looks like synchronous code with some help of the underlying runtime. (And no, ES7's async is not good enough for me here)

Sounds like a leaky abstraction. Easier to get started with maybe, but woe betide the legion of programmers who make assumptions based on the appearance of synchronous execution only to be left stranded when those assumptions don't hold.
Asynchronous execution isn't an unfortunate design choice to be papered over; better to make it as easy as possible to learn and work with.

When the event driven programming / promise hype started, I was like `Maybe $ exists thisConcept`

i love elixir actors / golang goroutines, since i don't have to give any special treatment to async operations.

NodeJS: you needed 5% of your code to be async, so we made everything async so you get to write awkward async-but-not-really code for the other 95%, too. That's better, right?
At least that's how it's always felt when I've used it for anything non-trivial yet well within its typical set of use cases.

Does elixir solve this problem? http://journal.stuffwithstuff.com/2015/02/01/what-color-is-y...
