Copy and paste error: this was missing:

require 'delegate'

class CiHash < DelegateClass(Hash)
  def initialize
    super({})
  end

  def []=(k,v)
    __getobj__[(k.downcase rescue k)] = v
  end

  def [](k)
    __getobj__[(k.downcase rescue k)]
  end

  # add other lookup and mutation methods
end


>  h = CiHash.new
>  h["FOO"]=1
>  h[:not_a_string]=2 # works, too
>  puts h["foo"]
>  puts h[:not_a_string]
