The Scala spectrum: OOP to Pure FP

Scala is a great language in many ways. One great feature is that you can use it as a “Better Java” (i.e., as an OOP language), and you can also use it as a pure FP language. While some people prefer one extreme or the other (not unlike extremist Republicans and Democrats in the U.S.), I appreciate that this lets you find a “Middle Way” of using the best features of both approaches.
