How to use the @esfx/internal-guards.isObject function in @esfx/internal-guards

function decorateMember(decorators: (PropertyDecorator | MethodDecorator)[], target: object, propertyKey: PropertyKey, descriptor?: PropertyDescriptor): PropertyDescriptor | undefined {
        if (typeof propertyKey !== "symbol") propertyKey = "" + propertyKey;
        for (let i = decorators.length - 1; i >= 0; i--) {
            const decorator = decorators[i];
            const decorated = decorator(target, propertyKey, descriptor!);
            if (isDefined(decorated)) {
                if (!isObject(decorated)) throw new TypeError();
                descriptor = decorated;
            }
        }
        return descriptor;
    }

export function hasInstance(value: unknown): value is Disposable {
        return isObject(value)
            && dispose in value;
    }

export function hasInstance(value: unknown): value is AsyncLockable {
        return isObject(value)
            && AsyncLockable.lock in value
            && AsyncLockable.unlock in value;
    }
}

export function hasInstance(value: unknown): value is Lockable {
        return isObject(value)
            && Lockable.lock in value
            && Lockable.unlock in value
            && (!(Lockable.tryLock in value) || !isDefined(Lockable.tryLock) || isFunction(Lockable.tryLock));
    }
}
