What Hacker News says?

In Scala you have value class, that get replaced by the underlying type during compilation so there is no overhead. https://ivanyu.me/blog/2014/12/14/value-classes-in-scala/ It may sounds a hassle but you only have to handle it at the interfaces (for example for a web app in the controller and data layer), in the rest of the code you just manipulate your value l…
