I think the way it splits up complex numbers can definitely help, if
you find them useful in your algorithm, but my experience so far with
futures suggests that putting things in Typed Racket won't necessarily
make it a whole lot easier to avoid barricades. It will, however, give
the same speedups that you were talking about, which is definitely
going to be helpful.

James is working on a visualizer that will help understand the
peculiarities of futures and I hope it'll be in a pushable state in
not too long.
