Tests would simplify the development, wouldn't they?
While working on mulitplication algorithm I found myself editing main.cpp to test changes. It would be more fruitful to save such investigations as tests.
They will also help the contributor to be confident he didn't break the results of previous investigators.
I can prepare a MR to show how it can work. @debol, @emortikov, are you interested?
