If not integrated in the language via keywords, how could one 
accomplish it using the "keywords" anyway? Could udas be used? 
@async @await?

Could "compile time magic" lower to something?

I find it hard to believe that it would be *impossible* since D 
is one of the most plastic statically typed languages I know.
