Difference between stack-allocated class and struct

[Sean Cavanaugh]

Here is my prototype COM compile-time reflection based wrapper mixin 
(which I have abandoned in favor of alias this since it covers 95% of my 
use cases even though it isn't perfectly safe).  I am new at D so you 
have been warned, though this part of the language seems pretty 
straightforward enough.  It is possible the track down the argument 
names but takes some rather intricate parsing to do correctly (and the 
example someone linked me in another thread of mine chocked on const 
types due to parsing bugs).

The wrapped interface also needs to be a mixin so it can be created in 
the correct module, with visibility to all the types passed to the 
interface's methods.


So something like the following is going to fail miserably unless ComPtr 
is also made into a mixin and instantiated in the correct module.


struct ComPtr(T)
{
public:
     T m_Pointer;
     mixin(WrapComInterface!(T)("m_Pointer")
};
