IMO the key is *virtual* methods, which require dynamic lookup in a Virtual Method Table or similar structure. In non-OO languages calling conventions like "call by name" also can require dynamic lookup of function addresses. Sorting and searching algorithms also typically are implemented with a compare function (pointer) argument. DoDi
