Maybe it's sufficient to show just *some* cool features/differences in
the greeter example.
I'd suggest:
 * slicing (could also show that arrays have a length)
 * some easy template-stuff
  - we allow types as parameters (of course), but also values
  - static if
 * scope guards
 * maybe closures (delegates)?
 * /what else?/
