Great stuff, Walter.
I hope you get 1.0 out before Google or IBM gets to you!

The scope stuff is very, very cool.

However, let me be a lone dissenter against the new if( auto = ) stuff.
My issue with it is what it may do to developers taking a peek at D.

C-Junkie: "Well there is my old reliable if statement...wait a 
minute...whats all this then?  This language is too weird, I am going 
back to my comfortable (language-X)."

This is yet another corner case bound to look small to experienced users 
but may shy away others from the language.

Again I vote for:

with( expression ) { ... } else { ... }

if expression is null then the else block is executed.

Of course, just my humble opinion.
