How do you append to a dynamic array using move semantics?

[cy via Digitalmars-d-learn]

struct Thing {
  @disable this(this);
}
...
items ~= move(item); // Error: struct Thing is not copyable 
because it is annotated with @disable

++items.length
move(items[$-1],item); // Error: struct Thing is not copyable 
because it is annotated with @disable

appender(items).put(move(item)); // Error: template 
std.array.Appender!(Thing[]).Appender.put cannot deduce function 
from argument types !()(Thing)

...?
