Cake pattern

(don't read this post if you are eating because it might make you throw up)

	trait DataReader {
	def readName(): String
	}
	trait DummyDataReader extends DataReader {
	def readName(): String = "bEllA"
	}
	class GreeterService {
	self: DataReader =>
	def greet(): Unit = {
	val formattedName = self.readName().toLowerCase.capitalize
	println("Hi there, " + formattedName)
	}
	}
	object Main extends App {
	val greeter = new GreeterService() with DummyDataReader
	greeter.greet()
	// if you want to know why people hate the cake pattern then here is the answer:
	greeter.readName()
	// wtf?! It exposes all the methods of all the dependencies! Grim
