What would you like explained? Or alternatively, which parts of 
the code *do* make sense to you?

A full explanation without making any assumptions about your 
background and experience, other than a minimal working knowledge 
of D, would be multiple pages long.

That is the goal of the full system, yes. The code in my original 
post isn't intended for practical use, though. It's just a 
demonstration of some bugs or missing features in the current 
implementation of `return`, together with a small demonstration 
of the practical value of fixing them.
