why can't I do some like typealias Nullable<T> = T? (it's kinda useless, but I have to do similar one)

What’s the actual example?

[streetsofboston]

Types can take parameters, but they can’t be a type-parameter themselves… Kotlin does not have higher-kind types…

[streetsofboston]

typealias is much like copy&paste, but I guess that the ‘pasted’ result still must be a valid type (and not a type-parameter).

[E.Kisaragi]

is it higher-kind type??
