title: Numpy ValueError: no fill-function for data-type
body: <p>I know it doesn't make sense, but I executed the command:</p>
  
  <pre><code>numpy.arange(0, 5, 1, numpy.bool_)
  </code></pre>
  
  <p>And it returned an error <code>ValueError: no fill-function for data-type.</code>. All data types seems to be working except boolean which return this error.</p>
  
  <p>I was expecting <code>False, True, True, True, True</code>, what causes that error?</p>
