Re^3: Happy 2006

The running time is about the same, but your solution uses a lot more memory, as it makes a list of all possible expressions to test before making the first test, while my solution tests each expressions right after it is constructed. My solution has a lot less pagefaults.

As pointed out, glob is an iterator in scalar context. However, for provides list context.
