This is *default* initialization, not per instance
initialization. The compiler will create one instance of B and it
will become the default initializer of b in *every* instance of
A. You can
Why:
enum Base {

D = 1, // Same error

void func(Derived d) {}
func(Derived.E); // works.

So this is mostly curiosity and not completely related to D but I
would like to know how a vtable is actually implemented. All the
explanations that I have seen so far are a bit vague and it would
be nice to actually see some code.

Hi !
I wonder if i can rely on this code :

There's two questions:
1) Is dtors always called in reverse order ?
