I've developed frameworks, and it's virtually impossible to anticipate all user requirements.

Never heard of source level as an adjective for polymorphism. What's it mean?

template<typename T> struct A { 
    T t; 
    A() : t() { t.foo(); }

struct B {
   void foo() { printf("hello!\r\n"); }
};

A<B> c;

struct B {
   void bar() { printf("goodbye!\r\n"); }

By this, do you mean that code that isn't used doesn't get linked into the .exe?
