I personally would vote against this. I do not think it's the role of a core language to worry about things like distributions, bias, and sampling. At the same time, I agree it's a very common task for playgrounds. I've developed a lot of material for everything from random colors and shapes to placeholder APIs to shuffles. Best regards, -- E
