 The `EarlyBinder` type provides an [`instantiate_identity`] function for discharging the binder when you are "already inside of it". This is effectively a more performant version of writing `EarlyBinder::instantiate(GenericArgs::identity_for_item(..))`. Conceptually this discharges the binder by instantiating it with placeholders in the root universe (we will talk about what this means in the next few chapters). In practice though it simply returns the inner value with no modification taking place.
