-#![feature(dropck_eyepatch)]
-
-// The point of this test is to illustrate that the `#[may_dangle]`
-// attribute specifically allows, in the context of a type
-// implementing `Drop`, a generic parameter to be instantiated with a
-// lifetime that does not strictly outlive the owning type itself.
-//
-// Here we test that only the expected errors are issued.
-//
-// The illustration is made concrete by comparison with two variations
-// on the type with `#[may_dangle]`:
-//
-//   1. an analogous type that does not implement `Drop` (and thus
-//      should exhibit maximal flexibility with respect to dropck), and
-//
-//   2. an analogous type that does not use `#[may_dangle]` (and thus
-//      should exhibit the standard limitations imposed by dropck.
-//
-// The types in this file follow a pattern, {D,P,S}{t,r}, where:
-//
-// - D means "I implement Drop"
-//
-// - P means "I implement Drop but guarantee my (first) parameter is
-//     pure, i.e., not accessed from the destructor"; no other parameters
-//     are pure.
-//
-// - S means "I do not implement Drop"
-//
-// - t suffix is used when the first generic is a type
-//
-// - r suffix is used when the first generic is a lifetime.
