+description:
+  This package provides a canonical anonymous 1-tuple type missing
+  from Haskell for attaching typeclass instances.
+  .
+  NOTE: There is also the </package/OneTuple OneTuple package> which
+  by using a boxed @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 'Only' is to
+  provide the traditionally so named type-wrapper for attaching typeclass
+  instances.
