how would I define a fun <T> where <T> is one of 2 or more unrelated classes? for example: <T> can be <String> or Map<*,*> but nothing else

if the map contains normal execution result and the string contains some error message or viceversa, you can use Either from funktionale https://github.com/MarioAriasC/funKTionale/wiki/Either

interesting, thanks

or fun<T> funName() where T : String, T : Map<*,*>

@menegatti That won't work, it requires T to extend both String and Map, which is impossible since String is a final class.

[menegatti]

good one, I completely missed that point

[kirillrakhman]

how about two overloads?

How about T : someSealedClass?
