Your example code doesn't even compile for me, I think because T is wrong? Or is value not supposed to be something like mapOf("x" to mapOf("y" to mapOf("z" to 5)))?

[karelpeeters]

But if I understand correctly this can be rewritten with `fold`:

private fun traverse(map: Map<*, *>, vararg keys: String): Any? =
        keys.fold(map as Any?) { m, k ->
            (m as? Map<*, *>)?.get(k) ?: return null
        }

[Brian Carbone]

mine definitely works but that looks nice too

[Brian Carbone]

you might not have been passing the map as <*, *>

[karelpeeters]

Yeah probably, but the way T is used here isn't right at all.

[Brian Carbone]

yes it could be ‘Any?’ without generics
