title: Automatically @synthesized properties in Xcode 4.4
body: <p>From the Xcode 4.4 release notes:  </p>
  
  <blockquote>
    <p>The compiler automatically calls @synthesize by default for unimplemented @properties</p>
  </blockquote>
  
  <p>What exactly does the new default synthesizer look like? Does it create a variable of the same name as the property (or does it prefix it with an underscore, which seems to be a good practice, but required extra typing so far)?</p>
