and that's not the case from the second level on.

This can be easily overlooked, hence my remark.

    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.
