BigDecimal doesn't count? (I guess because it's "Big" rather than efficient.)
d = a.add(b.mul(c));
d = a + b * c;
COMPUTE D = A + B * C.
They should retrofit it as follows:
interface Addable<T> {
T add(T other);
}
A java string added to anything results in the toString() method being called. It doesn't matter if the string is before or after the + operator. How do you specify precedence in this new scheme short of an exponentially large `add` method handling all the cases. And each add method has to handle all the variety of cases.
interface Addable<RHS, Result> {
Result add(RHS other);
}
