-// Issue 34101: Circa 2016-06-05, `fn inline` below issued an
-// erroneous warning from the elaborate_drops pass about moving out of
-// a field in `Foo`, which has a destructor (and thus cannot have
-// content moved out of it). The reason that the warning is erroneous
-// in this case is that we are doing a *replace*, not a move, of the
-// content in question, and it is okay to replace fields within `Foo`.
-//
-// Another more subtle problem was that the elaborate_drops was
-// creating a separate drop flag for that internally replaced content,
-// even though the compiler should enforce an invariant that any drop
-// flag for such subcontent of `Foo` will always have the same value
-// as the drop flag for `Foo` itself.
