Besides the pointer adjustment problem mentioned by
FeepingCreature, it's an unsound conversion even with just class
inheritance. Consider:
```
class A {}
class B : A {}
class C : A {}
void main()
{
auto bArr = [new B()];
A[] aArr = bArr; // If this was allowed..
aArr[0] = new C(); // This would be a problem, because bArray
would now contain a C.
}
```
