I agree it's cool, at least in a golfing sense. But is your explanation right? The *range* operator (`..`), if the rhs is less than the left, yields an empty list rather than iterating between the endpoints. In contrast, the *sequence* operator (`...`) iterates. So, in code: say [*]; # 1 say [*] (); # 1 say list 1..0; # () say [*] 1..0; # 1 say list 0..1; # (0 1) say [*] 0..1; # 0 say list 1...0; # (1 0) say [*] 1...0; # 0 say list 0...1; # (0 1) say [*] 0...1; # 0 -- love, raiph
