You can give a nested slice as a list and get the result similarly nested, however, this fails when you add any(?) adverbs and you only get results for top-level indexes​:

  m​: dd ("a".."z")[(3, (4, (5,)))]
  rakudo-moar 6bb1b5​: OUTPUT​: «("d", ("e", ("f",)))␤»
  m​: dd ("a".."z")[(3, (4, (5,)))]​:p
  rakudo-moar 6bb1b5​: OUTPUT​: «(3 => "d",)␤»
  m​: dd ("a".."z")[(3, (4, (5,)))]​:k
  rakudo-moar 6bb1b5​: OUTPUT​: «(3,)␤»
  m​: dd ("a".."z")[(3, (4, (5,)))]​:kv
  rakudo-moar 6bb1b5​: OUTPUT​: «(3, "d")␤»

  m​: dd ("a".."z").Hash{('a', ('m', ('s')))}
  rakudo-moar 6bb1b5​: OUTPUT​: «("b", "n", "t")␤»
  m​: dd ("a".."z").Hash{('a', ('m', ('s')))}​:p
  rakudo-moar 6bb1b5​: OUTPUT​: «(​:a("b"),)␤»
  m​: dd ("a".."z").Hash{('a', ('m', ('s')))}​:v
  rakudo-moar 6bb1b5​: OUTPUT​: «("b",)␤»

  m​: dd ("a".."z").Hash{('a', ('m', ('s')), 'u')}​:p
  rakudo-moar 6bb1b5​: OUTPUT​: «(​:a("b"), :u("v"))␤»
