title: python struct unpack into a dict
body: <p>struct.unpack will unpack data into a tuple.  Is there an equivalent that will store data into a dict instead?</p>
  
  <p>In my particular problem, I am dealing with a fixed-width binary format.  I want to be able, in one fell swoop, to unpack and store the values in a dict (currently I manually walk through the list and assign dict values)</p>
