title: Does begin . . . end while denote a 'block'?
body: <pre><code>temp = 98.3
  begin
    print "Your temperature is " + temp.to_s + " Fahrenheit. "
    puts "I think you're okay."
    temp += 0.1
  end while temp &lt; 98.6
  </code></pre>
  
  <p>In the above example, is everything between begin and end a block?</p>
  
  <p>I'm still confused what a block is.</p>
  
  <p>If you can't call it a block, what would you call that chunk of code between begin and end? Is it ok to call it a chunk?</p>
