enum with classes/structs

I don't think so. Enums are compile-time constants.
This code doesn't compile:

class A {
   this(uint i) {}
}
enum myEnum : A {
   entry1 = new A(0),
   entry2 = new A(1)
}
void main() {}

It's important to understand that in D OOP and procedural/C-style features are often separated. typedef didn't work well with OOP. Don't mix things that are not meant to be mixed.
