-/// The compiler previously did not properly check the bound of `From` when it was used from type
-/// of the dyn trait object (use in `copy_any` below). Since the associated type is under user
-/// control in this usage, the compiler could be tricked to believe any type implemented any trait.
-/// This would ICE, except for pure marker traits like `Copy`. It did not require providing an
-/// instance of the dyn trait type, only name said type.
