# Original version / new python implementation
./python -m timeit -s "from collections import namedtuple;a = namedtuple('a', 'a b c')(1, 2, 3)" "a.a"
10000000 loops, best of 3: 0.07 usec per loop


# C implementation
./python -m timeit -s "from collections import namedtuple;a = namedtuple('a', 'a b c')(1, 2, 3)" "a.a"
10000000 loops, best of 3: 0.028 usec per loop


The fallback is the same implementation that is currently used so this should have no affect on pypi.
