I need some insight into how COM objects interoperate with D, as well as 
some advice on how to manage them properly.

I've seen posts that IUnknown is treated specialy by the compiler, what 
is the nature of this behavior?   Does this include any kind of 
AddRef/Release behavior integration with the GC system or variable 
assignment, or is it purely for making interfaces have compatible vtbl's?

If the AddRef/Release management isn't automatic is there a library 
somewhere to help with it (i.e. a D version of ATL's CComPtr template, 
or code similar to it)?

I suspect the answers are somewhere I'm just not familiar with the extra 
libraries on dsource at the moment :)

I've done a bit of COM stuff (both implementing com objects and using others) in
Juno and it worked ok, though unfortunately it needs some changes to get it to
work with the current D2.
