>> Task.start(...)

> I almost never use task, because I like certainty. I've been bitten too badly by people using it who didn't understand it. I don't like having to explain `Enum.each(tasks, &Task.start/1 )` is going to screw up your order of operations to someone who doesn't get it.

I don't understand this. In any language with any concurrency support there's a point where you spin up a bunch of threads to do something. That's a useful capability and developers should understand it. If you don't know Elixir then you need to learn what Task does, but that's true in any language.
