ActiveSupport::HashWithIndifferentAccess#fetch

Same as <tt>Hash#fetch</tt> where the key passed as argument can be
either a string or a symbol:

  counters = ActiveSupport::HashWithIndifferentAccess.new
  counters[:foo] = 1

  counters.fetch('foo')          # => 1
  counters.fetch(:bar, 0)        # => 0
  counters.fetch(:bar) { |key| 0 } # => 0
  counters.fetch(:zoo)           # => KeyError: key not found: "zoo"
