Method `reduce` with `key/index`

[SDIjeremy]

Currently it is not possible to access the Key/Index of the item while using reduce()

$collection->reduce(function ($carry, $value, $key) use ($ratio) {
    return $carry + ($value * $ratio[$key]);
});

Hi. Thanks for reporting. Could you please provide an example on Runkit?

Notice how the Object logs the keys, but the Array does not. I understand that there are no keys on an array, but we should get the indexes instead.

Can you please check my PR, it says it failed but I can't see the error.
