it'd nice to have forEachIndexed offering immediately i, it

[benleggiero]

does it not?

I think Giuseppe wished this would be implicit, i.e. you could write:

list.forEachIndexed { print("index: $i, value: $it") }

as opposed to

list.forEachIndexed { i, it -> print("index: $i, value: $it") }

As my current favorite proposal is trailing commas, I wouldn't want this to be implemented tho, because I could not write:

list.forEachIndexed { i, it, -> print("index: $i, value: $it") }

ah, like Swift does with $0.0 and $0.1. I'd like to see it1 or it2

@mg6maciej exactly, what I meant was implicitness

[mg6maciej]

For me Python's Zen is quite important and this invalidates "explicit is better than implicit" rule.

I don't want implicit be mandatory, but I'd like to have the choice

[benleggiero]

I'd like to see, maybe, a way to tell the compiler "This parameter of the lambda is the `it`", so you could at least still use it in forEachIndexed without explicit naming
