It becomes apparent with more complex data structures, such as AoAoAoAoAoAoA's or HoHoHoHoHoHoHoH's, or any mutant variation thereof.      $data->[0]->[1]->[3]->[1]->[41]->[6] over      ${${${${${${$data}[0]}[1]}[3]}[1]}[41]}[6] Unless you're really good at counting brackets, I'd stick with the C-style dereferencing via '->'
