Content: First part of Tutorial. To show what is class and what is object and that all programs will be run as objects. Show Hello.scala example.

Some thoughts:

• in Scala everything is an object? Why should I care? --> uniformity, i.e. no special cases, ... what else?
• should we also say here that everything is also an expression?

val foo = if ... then ... else ...

Depends pretty much on the audience... I think it's good to mention this in the context of mentioning the benefits:

• everything is an object: no more boxing/unboxing - you can type-safely monkey-patch your own Int / String (implicits)
• everything is an expression: say goodbye to return :-D
