Linearization was covered in depth and you should be familiar with what to expect when using traits for multiple inheritance and why things work exactly the way they currently do.

Testing is an essential part of every good software project, and we also presented how it should be done for traits. Last, but not least, we prepared a few guidelines that should help developers choose between...
