If I have

sealed class Foo<T:Any> {
	object Bar : Foo<Nothing>()
	class Baz(val p: String) : Foo<String>()

	// I can do this
	fun String.convert() = this.let(::Baz)
}

// One type argument expected for class Foo<T : Any>
fun String.convert2() = this.let(Foo::Baz)

typealias FooBaz = Foo.Baz

fun String.convert3() = this.let(::FooBaz)

I get an error if i try

Foo::Baz

but adding a type makes

Baz

an unresolved reference. The code does work if all generics are removed. Can I fix this without import statements?

Would this work?

fun String.convert2() = this.let{Foo.Baz(it)}

You could try

Foo<*>::Baz

, and I believe it should work as expected
