StandardOperatorOverloader class final

The default OperatorOverloader: it takes over no operator, so arithmetic on operands without a built-in rule fails with operatorNotSupportedBetweenTypes (EL1030E).

Every context starts with it; replace it on a StandardEvaluationContext to give operators a meaning for your types.

// `{1} + {2}` is not supported by default.
const StandardOperatorOverloader()
    .overridesOperation(Operation.add, [1], [2]); // false

Spring (Java):
