I have a list of () -> Item lambdas and I want to map it like map { it() }. Is it possible to write this using a function reference? I was guessing something like map((()->Item)::invoke)

Thanks! Got me thinking that a typealias might also work, and it does:

private typealias ItemSupplier = () -> Item
val items = list.map(ItemSupplier::invoke)

What a hack 😂

Function0<Item>::invoke

@ephemient good to know, thanks. Though it’s good to know a typealias/interface is not needed, I’m thinking using a typealias is a little clearer. Perhaps generally whenever a lambda is used as a generic.
