The Tuple is good for returning multiple values without creating a class. The maximum number of values is currently 22. Which means that there is actually a type called Tuple22!
The option is a good way to avoid NullPointer-Exceptions.
The Pattern Matching is good for evaluating values.
The Exception handling is using pattern matching!
Enjoy! :-)
