Is there a common ancestor for String and Char?

[Rob Elliot]

Only really Any. Char represents a single character, String an immutable list of characters, so it's hard to see what common supertype they could have.

(They can also both inherit from Comparable<*>, but that's not a lot of use...)

pretty much. the variance is Comparable<in T> , so Comparable<*> is effectively Comparable<Nothing> which is useless 😄
