<p>
A comparison of two interface values with identical dynamic types
causes a <a href="#Run_time_panics">run-time panic</a> if values
of that type are not comparable.  This behavior applies not only to direct interface
value comparisons but also when comparing arrays of interface values
or structs with interface-valued fields.
</p>

<p>
Slice, map, and function values are not comparable.

interface{ ~[]byte | myString }           // bytestring
</pre>

<p>
Note that <code>bytestring</code> is not a real type; it cannot be used to declare
variables or compose other types. It exists solely to describe the behavior of some
operations that read from a sequence of bytes, which may be a byte slice or a string.
