// consequence, the class `Construct` in each copy of the `constructs` library
// is seen as a different class, and an instance of one class will not test as
// `instanceof` the other class. `npm install` will not create installations
// like this, but users may manually symlink construct libraries together or
// use a monorepo tool: in those cases, multiple copies of the `constructs`
// library can be accidentally installed, and `instanceof` will behave
// unpredictably. It is safest to avoid using `instanceof`, and using
// this type-testing method instead.
