Alternatively, you can @disable this(this), which would make copies illegal, 
but then I'd be worried about code breaking when the compiler adjusted some of 
its optimizations (though it would generally be unlikely for a move to become 
a copy - the opposite would be far more likely, which wouldn't break 
anything).
