Big W has said that he may allow object/method information to be queried in the future.  This is just an idea around that one.

Parhaps RTTI could be specified as an attribute as in:

class A
{
   rtti
   {
       int a; //rtti'd
       int b; //rtti'd
       int x() { return 10;} //rtti'd to look like a property
       void x(int x) {}       //rtti'd to look like a property
   }

   int c; //Not rtti'd
}

As far as accessing the meta-data, big W probably already has some good ideas on that.  If the rtti attribute doesn't exist then the class can be treated like it doesn't have rtti at all.
