Hello,
i know that in Ruby 1.9 Hash is ordered, but it seems to be a
controversial solution.
Does there exist by any chance any standard library with an OrderedHash
class?
I would prefer to call ordered hash an OrderedHash, rather than Hash.

I saw that there existed ActiveSupport::OrderedHash in Rails, but its
API page recently disappeared...

I think by the way that the current ordered implementation of Hash is
nice, but should have been called OrderedHash, so that in future
versions Hash could be made unordered again.

Thanks,

Alexey.
