Merging pull request highlight (#19)
Again did some formatting during tests, some comments on those
- As a rule I do not do assignments in tests, thats a bug waiting to happen.
- Iterating over const ref items can be a huge gain in big lists by preventing unneeded copies.

Then I have to thank Typz for this contribution. It is a very elegant way of doing it and it solves one of my most irritating issues not getting this to work. I like the suggestions comment when hovering over the mistake.
