// rust-lang/rust#47215: at one time, the compiler categorized
// thread-local statics as a temporary rvalue, as a way to enforce
// that they are only valid for a given lifetime.
//
// The problem with this is that you cannot move out of static items,
// but you *can* move temporary rvalues. I.e., the categorization
// above only solves half of the problem presented by thread-local
// statics.

        let _y = x.get_mut();
