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.
