// Checks if `x` is a construct.
//
// Use this method instead of `instanceof` to properly detect `Construct`
// instances, even when the construct library is symlinked.
//
// Explanation: in JavaScript, multiple copies of the `constructs` library on
// disk are seen as independent, completely different libraries. As a
// 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.
//
// Returns: true if `x` is an object created from a class which extends `Construct`.
