I don't completely agree; I don't think there's a need for an else part for

if C then
    return;
end if;

The idea that the programmer should show that the else processing has been 
considered and deliberately ommitted is good for most if statemwents, though. I 
follow the rule that an if with an elsif part must have an else part. When 
there's multiple branches it's important to show that you've considered them all.
