i guess this depends on what you have in your

apply

do you want to treat each element as

this

?

Yes, I want to apply something to every element of my collection. So if I could write

items.applyOnEach { this.attribute = "something" }

, that would be great

The method might no exist. I did not find anything worthwhile by googling

probably doesn't, just create your own extension

fun <T> Collection<T>.applyOnEach(block: T.() -> Unit) {
    this.forEach {
        it.apply(block)
    }
}

Or maybe make extension function on

it

to do the applying and pass that to the forEach

Yes absolutely, this is easily implementable. I’m just asking if it already exist. I don’t want to add noise in my code

I mean, you could do

inline fun <T> Collection<T>.forEachApply(block: T.() -> Unit

like said above, and it would work great
