Honestly, I've needed it many times and was surprised that it wasn't
implemented yet. Of course, there are a few ways you can do this (probably
more efficient way than what I suggested) but we also need to keep in mind
that we should keep our code as DRY as possible.

There is a reason why we have ordered hashes...

Ruby 1.9 onwards saves the insertion order of hashes. In fact in Ruby 2.1 - a
hash of under 6 elements is stored as an array ;)

Hashes are by definition unordered. If you think you need an ordered hash, then
you probably don't understand hashes...

You r
Having an OrderedHash that saves insertion order is useful enough and I
personally don't see a reason for a custom ordered hash.
Wouldn't it be less expensive to order only the keys in a separate array and
access the hash rather than creating a new hash?
My 2 cents.

Would a custom order of a hash be useful in Rails?
If I have the following Hash:
my_hash = { key1: 'value', key2: 'value', key3: 'value' }
And I want to order it by the following keys:
my_hash = my_hash.order(:key2, :key1, :key3)
I would get a new hash with the following result:
puts my_has
6 matches
