Ok, but it does look elegant and in one line.
That's how programs should look.
'The 'each' method can give me index of an element. I would use 'map' 
instead
but it can't give me index, just the element so I would have to create a new 
list.
I guess that would be pure functional and maybe more efficient in this 
case..
What are side-effects in this case ?

Just what I was going to try next.
