 * The **unconstructable** trait can be used to disable the ability to construct

 * final abstract classes and thus avoiding problems with non-final classes in
 * libraries that wish to adhere to SemVer semantics.
 *
 * The method is _final_ and _protected_ to avoid that subclasses overwrite it
 * and circumvent the restrictions laid out by the superclass.
