Paolo Xausa: Just a question: what is the preferred way to output a 2-d array, flattened or not? I see it done both ways; is there a preferred style?
15:51
Peter Luschny: I myself find this distinction extremely irrelevant. Anyone who uses the computer language used should be able to convert one form into the other. In the case of your current post, be able to delete or add "//Flatten". Some editors do not specify any output form at all, as you often see with lists where only the characterizing filter function is specified.

Paolo Xausa: Ok, thanks.
