You are asking us all to do work for you. You're asking everyone 
to learn about this new language element. (And yes, we would have 
to learn, since it means the compiler is less able to find errors 
in our code, because more code is valid.) You're asking Walter 
Bright or another compiler developer to implement this feature 
for you, and write the tests, and write the documentation, and 
support this new code for years.

This is not an impossibly huge request, but it isn't trivial by 
any means. There are two socially acceptable ways to get people 
to implement something you want: convince them it's worthwhile, 
or pay them.

Compare: there's no socket.io client or server library for D. You 
should implement one. Does my saying so make you inclined in any 
way to write a socket.io library?
