Documented applyMixins doesn't compile since TypeScript 2.7

[fer22f]

The following snippet from the handbook doesn't compile anymore:

function applyMixins(derivedCtor: any, baseCtors: any[]) {
    baseCtors.forEach(baseCtor => {
        Object.getOwnPropertyNames(baseCtor.prototype).forEach(name => {
            Object.defineProperty(derivedCtor.prototype, name, Object.getOwnPropertyDescriptor(baseCtor.prototype, name));
        });
    });
}

2.7.2 Playground
2.4.1 Playground

Any suggestions on how to fix it?
