Given an expression

someCollection.take(42).forEach { /* ... */ }

is there a way to access the collection inside the forEach that the forEach is iterating over?

someCollection
.take(42)
.let{ collection ->
    collection.forEach { item->
       // access to collection and item
     }
}

maybe something like this?

that could work in some cases, but it's a bit verbose 😕 was hoping for some kind of implicit variable inside the forEach block, like

it

...

you coiuld hide it behind extension

well

someCollection

will be in scope anyway

@Marcus Brito yes, but I think the point was to use the collection of size <= 42 returned by

take(42)

, not the original one

oh right, my bad

@Marcus Brito it's kind of hard to put into words: I'm dealing with lots of nested iterations over "views" of a single collection. For example, I could be like 5 iteration levels deep and would like the 6th level of iteration to start somewhere relative to the current one, and the current one relative to the previous one, etc... Right now I'm doing it "manually", with passing indexes everywhere and it's allright...

sound more like recursive function, maybe you should try to rethink the problem not the solution. 6 nested loops sounds like overkill
