Is there anything in the stdlib that captures the class and nullability of a type?

KType

would do that, but afaik the only way to obtain it without the reflection library is

typeOf

Thanks. I remember now that I was using KType, but it’s hard to get hold of one. Is this https://gist.github.com/udalov/bb6f398c2e643ee69586356fdd67e9b1 still the sanctioned way of converting a reified T to a KType please @udalov?

No, the stdlib has

typeOf

intrinsic now.

val myType = typeOf<List<String>>()

works fine

Ah, is still @ExperimentalStdlibApi I see but I’ll try it on for size. Cheers
