Actually, I find the typing discipline enforced by the monadic
abstraction very helpful (and elegant).

This sounds like a narrow (and C-ish) way to tackle things. The bind
operator is about composition of threads, not scheduling.

What you call the "call stack" is orthogonal to your "queues of
closures": one is about combining results of threaded computations
whereas the other is just spawning threads and relying on some external
mechanism to schedule them.

In other words, I think both can be used together, and achieve different
purposes.
