@Michael Theriot: It seems like this model can be abused in the same way that having separate methods for assign operators can be abused. I think having separate operators and automatically using `[[plusOp]]` if `[[assignPlusOp]]` doesn't exist is an easier programming model. People who need the extra performance can go the extra mile and define both operators.
