Ah, that makes sense. I'm not aware of this being requested, but that seems like a good thing to have.

It looks like this is implemented in Kotlin 1.3-M2 as I just tried it in IntelliJ with that version.

Never mind, the named argument at the callsite is what isn't allowed.

[Dico]

The problem is probably that the alias and type are interchangeable, so having a callBy functionality might require significant change.

In kotlin 1.3, you can try this if you don't need inlining of the function itself:

typealias ChangePortionCountValue = (increase: Boolean) -> Unit
inline class ChangePortionCount(val value: ChangePortionCountValue) {
    operator fun invoke(increase: Boolean) = value(increase)
}
fun something(changePortionCount: ChangePortionCount) {
    changePortionCount(increase = true)
}

Though, at that point, you can also just use an interface, actually. haha.
