title: Setting multiple object attributes at once
body: <p>Is there a way to set multiple attributes of the same object on a single line, similarly to the way one assigns values to multiple variables?</p>
  
  <p>If I can write</p>
  
  <pre><code>a,b,c=1,2,3
  </code></pre>
  
  <p>I would like to have something like</p>
  
  <pre><code>someObject.(a,b,c)=1,2,3
  </code></pre>
  
  <p>Having the same effect as</p>
  
  <pre><code>someObject.a=1
  someObject.b=2
  someObject.c=3
  </code></pre>
