I find myself usually finding an item by a variable and then return the variable itself, ie: `

items.list.filter { .. }.maxBy { it.depth }?.depth ?: -1

what about providing a maxOf((E)->T)?

We have it planned, but currently we're waiting for the compiler feature that would allow overloading on lambda return value.

anything where I can follow the progress?

.map { it.depth }.max()?

@ilya.gorbunov What would that compiler feature be necessary for? You can already write that operator now:

fun <E, T : Comparable<T>> List<E>.maxOf(mapper: (E) -> T): T? = map(mapper).max()

Or did I misunderstand what the operator would actually do?

[ilya.gorbunov]

Overloads may be required for Double and Float to handle NaNs correctly.

Ah, of course.
