title: Preserving White Space in qw
body: <p>Is there any way to preserve some white space in qw?  For example:</p>
  
  <pre><code>my @a=qw(1234 John Smith 123 Main St.);
  </code></pre>
  
  <p>will produce an array containing 6 elements.  Is there any way to, oh I don't know... escape the white space to keep some of it?  Something like:</p>
  
  <pre><code>my @a=qw(1234 John\ Smith 123\ Main\ St.);
  </code></pre>
  
  <p>to return 3 elements: '1234', 'John Smith', '123 Main St.'?</p>
  
  <p>(FYI, I've tried the above, also with varying combinations of quotes, all to no avail)</p>
