Hmm, I could use

let

, but I actually would like to use a non-extension function on my argument:

(listOf(1,2)).let { (x, y) -> x+y} //works
somefun(listOf(1,2)) { (x, y) -> x+y}  //want that

I don't think it exists in the standard library, but you can easily write it yourself:

inline fun <T, R> destructure(value: T, body: (T) -> R): R = body(value)

Thanks!

I don't know, sorry.

Last time this came up "is there a variant of run that calls a lambda with a given parameter?" the solution was to just call it yourself with

{ ... } (...)

, but this doesn't work:

{(a, b) -> a+b}(listOf(1,2))

Yeah, no "forward type inference" (yet?) 😞

I'm hoping this get's implemented some time, I needed it for some delegates too.
