raku has had feed operators like this since its inception

  # pipeline functional style
  (1..5)
    ==> map { $_ * 2 }
    ==> grep { $_ > 5 }
    ==> say();              # (6 8 10)

  # method chain OO style
  (1..5)
    .map( * * 2)
    .grep( * > 5)
    .say;                   # (6 8 10)

uses ==> and <== for leftward

true it is syntax sugar, but often the pipe feed is quite useful to make chaining very obvious
