There are faster ways of doing this, but only if you know the type of
object that you're accessing with the [ ].  Cython uses optimized
versions to access lists (and tuples I think), which do speed things
up.  The fastest is if it is a numpy array
(http://docs.scipy.org/doc/), where cython uses the underlying c
pointers to directly get the item, which is be orders of magnitude
faster.
