  The main benefit being we don't needlessly invoke `Proc.new` by omitting `&block` in the arguments. For more on this, read up on [Passing Blocks in Ruby without &block](http://mudge.name/2011/01/26/passing-blocks-in-ruby-without-block.html)
  
  Recursive `#each` is a powerful technique for providing a seamless, enumerable interface to paginated or cursored results.

  # command line
  export TRELLO_APP_KEY=your-key
  export TRELLO_APP_TOKEN=your-token
