This is fairly interesting. MS have extended their C++ compiler
significantly for Windows8 with a bunch of non-standard stuff.
FINALLY implement garbage collection, ref counting, properties,

If other compilers adopt this tech, D loses some advantages.
But you still have to fight with ifndef ,forward declaration, and a
template syntax against common sense. Even if you paint shit yellow
it's not necessarily gold.
True, but I think this will mitigate a lot of the motivation Windows
devs have to seek another language if they're not developing cross
platform apps.
Sadly, since WinRT requires using these language extensions to interface
with the new windows runtime, you won't be able to write a Windows8 app
in D.
Interestingly though, D supports almost everything they've added to C++.
I wonder if it would be possible to do extern(Windows8) to produce a
compatible ABI for linking with MS C++ apps?
The most interesting features are 'ref new' and 'gcnew', which makes me
wonder, since Windows8 has an OS garbage collector, would it be at all
possible to have D use the Windows8 GC? I'd prefer this to using D's own
GC if it would be supported, and obviously this would be a requirement
if D was going to interact with WinRT properly.
Also, WinRT uses 'ref new' to allocate ref counted (effectively COM to
my understanding) objects. I think I read somewhere that D already has
extern(COM) no? I wonder if Windows8 ref type linkage is already
technically supported in D?
It is an extension of the COM model. There is a new COM interface that
extends IUnknown, which provides a reflection API.
Everything is explained in the BUILD 2011 videos,
http://channel9.msdn.com/Events/BUILD/BUILD2011?sort=sequential&direction=desc&term=&t=c%2B%2B
Many of the new ideas are actually based on what Delphi together with
C++ Builder and VCL already provided.
Anyway this goes to show that eventually all system programming
languages will have GC or Refcounted memory management. As I already
mentioned here a few times when memory management discussions pop up.
