Multiple nil types in Go.

But: <a href="http://play.golang.org/p/J46-8OEWYS" rel="nofollow">http:&#x2F;&#x2F;play.golang.org&#x2F;p&#x2F;J46-8OEWYS</a>

In Go, nil is a value, not a type. Assigning &#x27;nil&#x27; to an interface only assigns the value, not the type. An interface has both a value and a type at runtime, but is &quot;nil&quot; only if both the value and the type are nil.
