in thread Modules to reduce syntax?

The -recurse option to h2o creates accessors for all levels of hash; though I have not tried to see if it works for something like, 
  my $ref = {
    foo => { bar => [ baz => 1, herp => 2, derp => 3 ], },
  };

Or maybe I don't know what you mean by, from the second level on.

    Your first level deref with H2O

    $ref->foo

    is 2 characters shorter than

    $ref->{foo}

    but that's it!

    No more gains for further levels

    $ref->foo->$bar->baz->bla °

    vs

    $ref->{foo}{$bar}{baz}{bla}

    is still only 2 characters better.
