<p> <p>
The functions <code>unsafe.Typeof</code>,
<code>unsafe.Reflect</code>,
and <code>unsafe.Unreflect</code> allow access at run time to the dynamic
types and values stored in interfaces.
<code>Typeof</code> returns a representation of
<code>val</code>'s
dynamic type as a <code>runtime.Type</code>.
<code>Reflect</code> allocates a copy of
<code>val</code>'s dynamic
value and returns both the type and the address of the copy.
<code>Unreflect</code> inverts <code>Reflect</code>,
creating an
interface value from a type and address.
The <a href="/pkg/reflect/"><code>reflect</code> package</a> built on these primitives
provides a safe, more convenient way to inspect interface values.
