Scala Dependency Injection: an improved cake pattern
View cake_pattern_di.scala
//harry huang []
//After reading the original post [, ]
//the original cake pattern seems quite verbose for me, and it is quite invasive, so I spent a bit time
//and come up with an improved version of cake pattern, which I call it a "Auto Cake DI". It is working
//well with any POST(plain old scala trait)/POSO(plain old scala object) which means that anything can be
//injected without modification or introducing new traits.
