Class or method to convert hash keys to enable either string or symbol access?

ruby-talk
1

I think I've seen this somewhere, but I can not recall where. Is there
some sort of class or method that will convert a hash so that all keys
may be accessed via a String or a Symbol, where the two are mapped
intelligently, and automatically upon assignment/creation of a key?

So like:

   h['A key'] == h[:a_key]

?

I usually use 'hashie' gem for this kind of stuff eg.

class Hash
  include Hashie::Extensions::SymbolizeKeys
end

or,

  class Hash
    include Hashie::Extensions::MergeInitializer
    include Hashie::Extensions::IndifferentAccess
  end
etc.
