+Haskell for attaching typeclass instances.
+
+There is also the @url{https://hackage.haskell.org/package/OneTuple, OneTuple
+package} which by using a boxed @code{data}-type provides a 1-tuple type which
+has laziness properties which are more faithful to the ones of Haskell's
+native tuples; whereas the primary purpose of @code{Only} is to provide the
+traditionally so named type-wrapper for attaching typeclass instances.")
