Why isn’t `chronosInternalRetFuture` gensymmed?

If you take the body of a procedure after it is processed by .async, put it into a new procedure, and apply .async to it, chronosInternalRetFuture will refer to the wrong variable. std/asyncmacro does not suffer from this.

P.S. If you are curious, I’m trying to make my asyncIters library work with Chronos.
