On the one hand it would be nice to have these methods, on the other
hand it would mean that Hash isn't anymore just simple, plain Hash
(because the can be sorted and who knows what else will in the
future). My pragmatic approach tells me that it's not as bad idea to
have it. Without it if someone want to change order of keys he can do
this by:

h = {"b" => "bar", "a" => "foo"}
h = Hash[*h.sort.flatten]
p h
