<@U5XDSK718> <@U5UU34LPK> Thanks. I tried already a `listOf` solution and it didn't work because of inheritance. Well, I guess then the simple `is` solution is directly readable and I stick to this. Thanks for your efforts :slightly_smiling_face:

the `when` solution was at least a little bit more concise

Ahh, damn. I don't use Slack that often and I haven't seen the direct reply. Thanks for throwing it into my face

But this one works well with inheritance. No?
```val v = HashSet&lt;String&gt;()
listOf(String::class, Set::class).any { it.isInstance(v) }```

It’s shorter. Looks not good because of `::class`. And I don’t know if it will require kotlin-reflection as dependency.

As for problem I think it must be solved via common interface, and not if-is’s.
