I definitely agree with you, so let's use what we know of Raku to our
advantage. A hash structure would work well, here with the
Array-Indexes-to-Use as keys:

class AA {
  has @.I;

  submethod BUILD (:$data) {
     @!I[.key] = .value for $data[]
  }

  method new (*@data) {
    self.bless( data => @data )
  }
}

You can now do the following:

AA.new(2 => 'b', 4 => 66, 9 => 'apples')

Which makes for a nice initializer!
