Well, both accomplish different things. In the first example, one and
only one of the conditions will be executed. In the second one, more
than one could possibly be executed.

I've never looked at Sieve's code, but the first will stop at the first
matching condition. In the second case, because you could make it do
more than one thing, it must check each condition.
