Very nice. Very nice.

I am noob in programming, passed some harder challenges before, but maaan, it took me many-many hours to figure out, absolutely drove me crazy and felt the best when passed all tests, awesome kata. Thanks!

This seems too complex for a 7 kyu, I think it should be 6 kyu.

I wasn't sure whether it's better to leave it as plain old "arr" or make it more specific. I trust your judgement in this matter so thank you for changing it.

@saudiGuy Yes, thank you. I looked up the improved code on my phone and I unwittingly approved the solution, so I didn't notify you. I wanted to accept it anyway; I only changed the "Pyramid Test" to "Fixed Tests" to really drive home that the tests are unmutable. Also, thanks for making the code better structured.

done.
