/**
 * This exhibits a regression case, that albeit weird, is valid according to the JSR 330 spec. JSR
 * 330 specifies a rough ordering by which members should be injected, and it is possible to rely on
 * such ordering. When members injecting [Subtype], field injection is guaranteed to be performed on
 * [Base] first. The binding for `@FirstToString` in [ ][OrderingModule.provideToString] relies on
 * this ordering, and thus uses the value in [ ][Base.first] to satisfy the binding.
