It doesn't? x?.toString() can return null, x.toString where x:Any? will return "null" instead.

[Ruckus]

You misunderstood. There is a defined

fun Any?.toString(): String

in the standard library

[karelpeeters]

Yes, that's my second example.

[Ruckus]

Yes, and @Dias was referring to the definition Any?.toString(), not to the call x?.toString()

[karelpeeters]

Hmm, I guess I see what he means. I meant the ?. at the callsite simple smile

[Ruckus]

Indeed. I think this distinction between definition and call site is more confusing than the returned value 🙂

[karelpeeters]

Agreed!
