It would be wasteful to write an OS to prove the claims. Unless there is 
a technical impossibility, then it's doable.

Let's do it the other way: What proof there is for the claim that those 
languages cannot be used for writing OSes? I know D enough to know that 
it can be used to manage a CPU, send electrical signals to all the I/O 
devices around it, etc.
