vtable

The "internal structure" (the object) then only needs one extra field: the compiler-generated hidden vtable pointer.

You can use subqueries today in InfiniDB by setting our vtable mode to pass everything to MySQL, but trust me: you don't really want to send subqueries against TB's of data and billions of rows directly to MySQL for processing unless you plan on waiting a while for your response.

With this design, there is no need to have a parent Tracer class - though I'd welcome having C++0x concepts available -, and the callbacks can be easily inlined because there is no run-time vtable lookup.

I knew from the very beginning that such an implementation was going to be inefficient due to the pointer dereference at each instruction and the vtable lookup for the correct virtual method implementation.

Note that if a method declared as pure virtual in class X then if an implementation of that method in class X is provided then it * does not* get called through the vtable, i.e. the body of that method is effectively a non-virtual method, to get called it has to be explicitly called somehow.

It also removed any semantic analysis we didn't think was essential for intellisense (initialization, member offset computation, vtable production, etc).
