If multiple inheritance is deemed complex, adaptation is even more so:

  With multiple inheritance, you can quite easily see from the source
  code how things are put together.
  Adaptation follows the "inversion of control" principle. With this
  principle, how a function is implemented, is decided outside
  and can very easily be changed (e.g. through configuration).
  This gives great flexibility but also nightmares when things do
  not work as expected...
