This does not seem simpler to me, this seems easier to mess up. The most common use case is dropping all fields.

Furthermore, you still have to special-case Drop because now you have to support destructive destructuring for Drop types because it isn't allowed anywhere else.

And plus, if you forget to do this, the failure mode is a stack overflow.

The current design is absolutely based on practical requirements here, it is not a retroactive justification. This is by and large how destructors work, for good reason.

Ah I meant to write the function signature:

> fn drop<T>(T);

contrasted with the:

> fn drop<T>(&mut T);

that we have today
