title: Is the question mark operator ? equivalent to the try! macro?
body: <p>I am looking for a way to chain the usage of the <code>try!</code> macro in Rust and found <a href="https://github.com/rust-lang/rust/pull/31954" rel="noreferrer">this pull request that implements the <code>?</code> operator</a>.</p>
  
  <p>It seems like it has been merged, but I cannot seem to find any documentation on it yet. Is it equivalent to the <code>try!</code> macro or are there important differences?</p>
