title: F# Idiomatic Index plus one when printing an index
body: <p>Is there a more idiomatic way to print an index +1 value with F#?</p>
  <pre><code>let plusOne i = i + 1
  let collection = [1..10]
  
  collection |&gt; List.iteri (fun index value -&gt; printfn &quot;%i %i&quot; (plusOne index) value)
  </code></pre>
