So, send (not in time) executes the handler immediately and awaits its completion returning the "return XXX" value in the result? WOW, I read the books and completely missed that if my understanding of what Scott Dar is saying.
Any resemblance between the above views and those of my
employer, my terminal, or the view out my window are purely
Any resemblance between the above and my own views is non-deterministic.
The question of the existence of views in the absence of anyone to hold
is left as an exercise for the reader. The question of the existence of
is left as an exercise for the second god coefficient.
