  • Okay, so we've established that: $x = any(3,4,5); @l = $x.values.sort; Leaves us with @l == (3,4,5), and that makes a fair amount of sense. What do the following evaluate to: @l1 = ...

  • Just a quick question: Is Hash keys still Strings, or can they be arbitary values? If the latter, can Int 2, Num 2.0 and Str "2" point to different values? Thanks, /Autrijus/
