But it is EXPLICITLY LEGAL to assign a literal to a mutable array. There is an
invisible dup by design. I don't like this, I argued strongly against it, but
it's in there. This isn't wrong code.
(Similarly, you can write const C x = new C; The C will be allocated on the
heap, even though it will never change afterwards).
