Good way to get *any* value from a Java Set?
Given a simple Set, what is a good way (fast, few lines of code) to get any value from the Set?
With a List, it's easy:

return things.get(0);
But, with a Set, there is no .get(...) method because Sets are not ordered.

What is the different between the following Generics definitions in Scala:
