title: NumPy "record array" or "structured array" or "recarray"
body: <p>What, if any, is the difference between a NumPy "structured array", a "record array" and a "recarray"?</p>
  
  <p>The <a href="http://docs.scipy.org/doc/numpy/user/basics.rec.html">NumPy docs</a>  imply that the first two are the same: if they are, which is the prefered term for this object?</p>
  
  <p>The same documentation says (at the bottom of the page):
  You can find some more information on recarrays and structured arrays (including the difference between the two) <a href="http://wiki.scipy.org/Cookbook/Recarray">here</a>. Is there a simple explanation of this difference?</p>
