Yeah, the post went steeply uphill there. But you can actually understand the gist of most of what he's saying without actually understanding what it means that "views don’t chain. Instead, use view bounds". And somewhat further on, it goes downhill again. In the simplest form, you can use Scala as a better Java. It's worth exploring it just for that comparison. And then there's much, much more you can do, if you want to, but it's also a very nice language if you don't try to add methods to the collections library and don't use dependent types.
