I know it sounds stupid, but following are 2 scenarios.

I wonder why the compiler complain about 1) but on 2) there is nothing?

Obviously on 2), T can't be null

In the first case, the compiler knows the type of hey, because you declared it to be String (non-null). In the second example, the type parameter could be anything, including a nullable type. val s: String? = null; s.doOrLog() is valid, type type parameter is just String? instead of String. You’d have to give the type parameter a bound of T : Any to declare that the type parameter should be non-nullable
