Yes, currently doing something similar to that, but I'd much rather have it as a first-citizen feature. Returning result directly from main sounds very interesting! I will have to look into that thx.

EDIT: I assume you mean RFC1937? Looks like it isn't implemented yet, so we will probably have to at least another year before we can get it in stable rust. But yes - without having read the entire RFC - I think that was what I was looking for!
