I thought it was a little strange that it was *exactly* the same, given the
function call...
Corrected (still not much difference, though):
...>python timeit.py -c -s"import flatten" "flatten.pro_dict()"
100 loops, best of 3: 7.22e+003 usec per loop

Well, should have made it sooner. I would have noticed an empty list...
