  <pre><code>(** [insert k v m] is the same map as [m], but with an additional 
      binding from [k] to [v]. If [k] was already bound in [m], that 
      binding is replaced by the binding to [v] in the new map. *)
  val insert : 'k -&gt; 'v -&gt; ('k, 'v) t -&gt; ('k, 'v) t
  </code></pre>
  <p>when I say <code>dune build</code> it gives error</p>
  <pre><code>Error (warning 50): ambiguous documentation comment
