• Automatic measurement of the speed (timeit)

It would be really nice to automatically measure the spped of the different solutions. In particular in the speedy section. So for each problem we would really know which solution is the fastest.

You could just run timeit (http://docs.python.org/2/library/timeit.html) the checkio method on few arguments.

Don't know if it is possible to do the same for memory space.

That would really be gorgeous.
