+Therefore, because of this ambiguity, such cases were forbidden in the first version of inline classes.

+However, since 1.8 these inline classes are mapped to the upper bound of the generic parameter.
+In other words, given the code

 * Sidenote: maybe it's worth to consider inline classes with reified generics:
