  Creating a new instance using the data from another instance is
certainly not delegation. It's just (partial) copying.

  If you make string a="abc"; string b=a; you are *copying* the
contents of a to b. That's not delegation.

  Sure you can misuse inheritance in all kind of ways, but that doesn't
mean all those wrong ways of using it are what inheritance was created
for.
