For mathemathical functions with a simple enough control flow, I'm  
ambivalent on the topic. However once a method has a premature return (or  
four) somewhere, the inconsistency hurts my sensitivities. Using the  
keyword in such a method as a matter of style gives me one less thing to  
keep in my head when scanning the code for exit points - either there is  
only one and it's completely obvious like in your example, or it's every  
line with "return" in it.
