ActiveSupport::OrderedHash disappears?

Rails
1

I noticed that ActiveSupport::OrderedHash disappeared from the Rails API
pages.
Does it mean that it is going to be deprecated?

I know that Hash is ordered in Ruby 1.9, but this subject seems
controversial, and in my opinion the ordered hash in Ruby 1.9 should
have been called OrderedHash (or SequentialHash), even if it be an alias
of the current implementation of Hash.
That way one would be free to return to unordered hashes in future
versions of Ruby.

I am considering using the ordered hash to store an ordered attribute
list with their types, to be able to render their values in a table in
the selected order.
(This is going to be a constant hash.)
I would like to write explicitly in my code that i am using OrderedHash.
So, is Rails going to continue implementing ActiveSupport::OrderedHash?

Thanks for any information,

Alexey.

In Ruby 1.9, the Hash just maintains insertion order within the hash and
not content ordering (i.e. key and values). Next, OrderedHash acts very
similar in nature to Hash in Ruby 1.9.2 and OrderedHash was being
used for backwards compatibility with Ruby 1.8.7.

If you’re using Ruby 1.9.2, it doesn’t matter if you’re using Hash or
ActiveSupport::OrderedHash because both will yield the same result.
Furthermore,
if you declare this as a constant, then you’re saying to the users of
the
code
that this will not be modified.

Good luck,
