digitalmars.D.learn - any way to initialize an array of structs to void?

reply ref2401 <refactor24 gmail.com> writes:
struct MyStruct {
	 disable this();

	this(int a, string b) {
		this.a = a;
		this.b = b;
	}

	int a;
	string b;
}

I know there is a way to create one instance of `MyStruct` and 
initialize it to void.
   MyStruct s = void;
   s = MyStruct(5, "abcdef");

How can initialize an array of `MyStruct` instances to void?
   auto arr = new MyStruct[10]; // compile-time Error: default 
construction is disabled for type MyStruct.

MyStruct[10] arr = void;

Don't do this with a dynamic array, though, as they work a bit 
differently from static arrays.

Unfortunately I have to deal with dynamic arrays.

In that case, you can use std.array.uninitializedArray or 
std.array.minimallyInitializedArray as needed.
