Thomas 'Pointed Ears' Lahn already gave a good answer in <news:1590597.KOVAYohEvS@PointedEars.de>: | Inherited methods can be reused. In this example, one advantage is | that only one Function instance is created, which saves memory as | compared to the instance method approach. It also saves runtime | because the creation of that object only happens once. (There are | also disadvantages.) -- Christoph M. Becker
