A modern programming language that makes developers happier.

kotlinlang

is it possible to have generics that need to fulfill one upper bound _or_ the other? With where clauses you can only specify multiple upper bounds that all need to be fulfilled at the same time

Sounds like a code smell. What do option A and option B have in common with each other?

they have in common that they are both classes from the android API, which smells to high heaven, unfortunately I can not change that. The new arch `ViewModel` only seems to works for `Fragment` and `FragmentActivity` but they have no common interface
