hash[:key_1] # => 1
hash.key_1   # => 1

hash[:key_2] # => {key_3: 3}
hash.key_2   # => {key_3: 3}

hash[:key_2][:key_3] # => 3
hash.key_2.key_3     # => 3 

Builder

hash = Hash::Builder.build do |h|
  h.key_1 1
  h.key_2 do
    h.key_3 3
  end
end

hash # => {key_1: 1, key_2: {key_3: 3}}

Normalized

hash = Hash::Normalized.new { |key| key.upcase }

hash['key_1'] = 1

hash['key_1'] # => 1
hash['KEY_1'] # => 1

Indifferent

hash = Hash::Indifferent.new

hash['key_1'] = 1
hash[:key_2]  = 2

hash['key_1'] # => 1
hash[:key_1]  # => 1

hash['key_2'] # => 2
hash[:key_2]  # => 2

Sorted

hash = Hash::Sorted.asc { |k,v| k.to_s }

hash[:c] = 1
hash[:b] = 2
hash[:a] = 3

hash.keys # => [:a, :b, :c]

Nested
