      # Special character to flag lines that are part of a multiline HEREDOC interpolation
      # Any character that is not part of the output string will work.  Using "\r" because
      # it's rarely used in hard-coded strings.

# The following code lets you iterate over large collections of Active Record 
# objects without having to load them all at once, thus reducing memory usage. 
# It’s allowed me to run cron jobs which iterate over thousands of records 
# without getting the cron’d process killed for using too much of a system’s 
# resources.

Surround a heredoc with quotes and you can continue the code on the same line:

    render :status => 404, :text => <<-'EOH' and return unless setup
        article not found<br/>
        I, as a server, have failed<br/>
        https?
        EOH

Quotes also give you more freedom/creativity with the terminal ID:
