module Hashie::Extensions::IndifferentAccess

IndifferentAccess gives you the ability to not care whether your hash has string or symbol keys. Made famous in Rails for accessing query and POST parameters, this is a handy tool for making sure your hash has maximum utility.

One unique feature of this mixin is that it will recursively inject itself into sub-hash instances without modifying the actual class of the sub-hash.

@example

class MyHash < Hash
  include Hashie::Extensions::MergeInitializer
  include Hashie::Extensions::IndifferentAccess
end

h = MyHash.new(:foo => 'bar', 'baz' => 'blip')
h['foo'] # => 'bar'
h[:foo]  # => 'bar'
h[:baz]  # => 'blip'
h['baz'] # => 'blip'
