Hi,
couldn't resist to announce that this little optimisation is now in
cython-unstable. An example of a corresponding for-in loop is below.
Have fun,
Stefan

__pyx_t_1 = 0;
__pyx_t_2 = 0;
__pyx_t_3 = 0;
for (__pyx_t_4 = 1; __pyx_t_4 < 5; __pyx_t_4+=1) {
__pyx_v_d = __pyx_t_4;
__pyx_v_c = __pyx_t_3;
__pyx_t_3 = (__pyx_t_3 + 1);
__pyx_v_b = __pyx_t_2;
__pyx_t_2 = (__pyx_t_2 + 1);
__pyx_v_a = __pyx_t_1;
__pyx_t_1 = (__pyx_t_1 + 1);
