ruby 你有一个深层嵌套的结构，你想从内部深入了解一个值吗？如果路径坏了，不在乎？用digg！我特别喜欢这个

module Digg
  def digg(*path)
    path.inject(self) do |memo, key|
      (memo.respond_to?(:[]) && (memo[key] || {})) || break
    end
  end
end

Array.send :include, Digg
Hash.send :include, Digg

# Use as
some_complex_json_rsponse.digg('preview', 'thumbnail', 0, 'id')
