I was going to write a post about generic copy operations.
But then I read Strategic Scala Style: Principle of Least Power and a light bulb went off. More accurately, I read it a couple of days ago, and today I had an ‘Aha!’ moment.
Just use a bloody function.
I model with traits too much. I guess it is a habit I acquired by extended exposure to Java.
I don’t have a problem using an API with functions, it’s one of my favorite things about Scala. I just don’t use them enough in my own APIs. Passive versus active vocabulary.
So I am writing this down instead: I need to use functions more.
