title: Will java allow to use functional interfaces as methods?
body: <p>With the new java lambdas and the concept of functional interfaces, will it be possible to treat those functional interfaces as methods? </p>
  
  <pre><code>interface Func { void execute(int i); }
  
  void call(Func f)
  {
      f(1); //instead of f.execute(1);
  }
  </code></pre>
  
  <p>I found a lot of information about the syntax of actual lambda expressions, but nothing about this.</p>
