Support for hashrefs hidding inside of arrays

[oodler577]

@haukex I created this issue in the Util::H2O::More repo, but I wanted to get some input - I really think it should be a modifier similar to -recurse but something that implies it'll do a full tree search of the ref (HASH or ARRAY) and turn all HASH refs it finds into a bless'd reference with accessors. I am finding a lot of JSON APIs present their results as arrays of hashes (when results are record oriented, which is often).

Would something like this fit in Util::H2O more than ::More?

Oh, with complementary support with something like o2h to undo it.

Another use case would be to allow for h2o'ing contents of @_in asub, but that might require h2o` to ignore some stuff;

consider,

sub foo {
  my ($self, $bar, $baz) = h2o -list-mode, @_;
  ..
  return $bar->some_attribute * $baz->some_other_attribute;
}

But $self would need to be ignored; main point is to use h2o as a filter for parameter lists, acting upon them only if it would have normally. I had not thought of this general application, but h2o -some-modifier ARRAY seems to be an interesting and useful idiom.
