      The new <a href="/pkg/go/types#Alias"><code>Alias</code></a> type represents type aliases.
      Previously, type aliases were not represented explicitly, so a reference to a type alias was equivalent
      to spelling out the aliased type, and the name of the alias was lost.
      The new representation retains the intermediate <code>Alias</code>.
