title: What is `scipy.i`?
body: <p>Out of random keyboard bashing, I ended up noticing that there is a variable in <code>SciPy</code> called <code>i</code>, which is assigned to the string <code>'6'</code>. (May be different on other machines?)</p>
  
  <p>I tried using built-in help functions, but there is nothing assigned to <code>scipy.i</code> as it only refers to a string.</p>
  
  <p>I also searched the docs and Google, but nothing came up.</p>
  
  <p>Could it be related to version control, or something similar?
  By the way, I'm using Enthought Python on Windows 7 (both 64 bits).</p>
  
  <p>This is far from being a critical question, I'm just curious about it!</p>
