Thanks for all the feedback on zebra stribes. What I meant as the learning experience was not so much the stribes themselves, but the fact that I could not find them. The reason I could not find them is because they are not there. I knew that Spec2 is not completely done, so I am not surprised that they were not there.
What I meant to say was that a method “beZebraStriped” could be put in, with an error message saying “not implemented yet”. Then I could stop looking around. And that goes for any aspect not yet implemented. Best, Kasper
