Could you also handle ConstantKind::Val?
The fact that const-prop does not replace Unevaluated by Val in this very case is not documented, and may change by accident.

I specifically do not want to handle it. I removed the logic that allows destructuring ConstValue except for pretty printing. I am currently working on eliminating this simd_shuffle special case entirely by making it a real const generic. That should avoid any such issues
