Anyway: you cant put a default destructor on struct

@property
B b() {
if (_b is null) _b = new B();
return b;

This exact same issue also crops up for classes, since
typeid(T).initializer is simply blitted over the newly allocated
memory. At least for classes we could change the language such
that:
class C {
int[] p = new int[5];
}
is sugar for:
class C {
int[] p;
this() {
p = new int[5];
}
}
No such solution exists for structs, since they don't have
default constructors.
