Exactly my thoughts. I studied a bit what's done in Brakes and IMHO what 
brings complexity here is that a thread can be suspended/resumed at any 
point of its execution, and I believe continuations are easier to 
implement since they are suspended and resumed in well-kown places.

This is one of my current background thinkings, and I plan to prototype 
something if - as always - I find time for it.
