>Pyrrhic victory

perhaps a tad hyperbolic? OP asked for reduction in syntax (I read it as more readable) - not even "less typing"; but the only thing I can assuredly tell you is that I tend to use this module a lot nowadays. And it is true that eliminating a paired set of curlies in exchange for some dereference syntax is worth it to me; and "overhead" (whatever that means to the reader) is generally never something I even look at. My optimizations happen on the algorithmic or complexity level; IOW I avoid nesting loops in favor of ... hashes (and references to such) :-) In any case, I should have added a YMMV.

    well you said

    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.
