But I see another case where assignment inside of expression would be helpful. It’s

when

expression with assignment: https://youtrack.jetbrains.com/issue/KT-4895 There is a big dissussion and looks like assignment inside

when

is the best proposal imho. Probably, if Kotlin team decide to implement this for

when

it would make sense to do also for

if

I would use that many times already if it’d exist:)

Yes, exactly. Case with

when

looks like much more common and important than

guard

for

if

Especialy when using

fun test () = when () {}

syntax:)

But for when again, I see why this is not really high priority feature. Because you can just create local variable before when

I know, it’s just a syntax sugar in this case, that you don’t have use block body

yeah
