Is there a trick to get use T? in a place where you need T?
Unfortunately there’s no T! 😄

Alternatively in a function where I want a non-nullable T for reified T: Any?.

Basically T & Any.

Constrain TFoo to Any?

[Marc Knaup]

Not possible in my context. Let’s take the function with reified parameter example. That’s easier 🙂

Let’s say I need a typeOf of non-null T without reflection, but T must be nullable in the same function.

Then constrain T to Any and use T? in the function

[Marc Knaup]

That would always make it nullable, which is not desired.
T may or may not be nullable.

What is Nothing?!? 😄

Just like everywhere else in Kotlin - something that you could construct that that throws a neat exception if you try to use it 😛

Or just while (true) { }
