Re: Is there a way to switch a hash values <> keys with a slice?

reverse is your friend, but hashes have no order so your sort is for vain. .

main::(-e:1):   0
  DB<1> @h{ a..c } = 1..3

  DB<2> x \%h
0  HASH(0x33c38e0)
   'a' => 1
   'b' => 2
   'c' => 3
  DB<3> %h2 = reverse %h

  DB<4> x \%h2
0  HASH(0x3554090)
   1 => 'a'
   2 => 'b'
   3 => 'c'
  DB<5>

you should also keep in mind that hash-keys are unique, any repeated value from the old hash will overwrite the last key-instance in your reversed hash. (the only way to avoid information loss is a hash of arrays `$h2{val}=[k1,k2,k3,...]` but this requires more code.)
