How can I achieve something like this without using out?

[karelpeeters]

Can you give us the types of all the relevant stuff?

[Dico]

The problem is that Column<String> cannot store Any? so you must declare the type as Column<out Any?>

[Dico]

We're using callsite variance here because the variance isn't specified like that in declaration site

[Dico]

The compiler is resolving the type to Column<out Any> because Any is the first common parent of String and Int, but the type Any can't be accepted by either object as a parameter where the type is T (in position)
