Well, I guess for the same reason that unary_traits and binary_traits 
are 2 classes instead of one. :)
You never need both at the same time, so one of your operator() is 
always superfluous.
Even from the standpoint of intuitivity of usage, I thought it'd be 
better to separate them into two classes. But maybe that's just me.
