This must be my math background confusing me. Conventionally, a+a is 
written as 2a, and a*a is written as a^2 (or a**2). Of course, if you 
recognize that concatenation of sequences is really a multiplication (by 
convention in mathematics addition is always a commutative operator), 
a*2 makes sense. I guess I'll change the way I write this in the future.
