Here's list what happens:

  1) Array gets sorted
  2) Duplicate elements gets removed (only unique stay)
  3) Then it get's maped by delegate. It converts numbers into 
strings.
     `r` variable will be ["3", "5", "6", "8"]

Item type is inferred from `set`, it's just syntactic sugar. Of 
course you can use `auto` but you don't have to.
