You have to fill in object.di's RTInfo(T) to be whatever you want.  As I  
said, it's very beta, intended as a hook to use for more precise garbage  
collection, or any other runtime info goodies you want to put in there.   
See my example for a hint.

Essentially, the compiler's going to do this:

class C {...}

// compiler: hmmm... have to generate TypeInfo_Class for C.  Let me set up  
all the normal hooks

TypeInfo_Class CTypeInfo;
CTypeInfo.name = "C";
...

// compiler: ok, now let me generate the RTInfo part
CTypeInfo.m_rtInfo = RTInfo!C;

Now, you can call typeid(instanceOfC).rtInfo and it will give you the data  
that comes from RTInfo!C.  And you don't have to know the type of  
instanceOfC, it could be Object.  It's essentially a way to convert  
compile-time data into runtime data.
