<h3 id="path_filepath">The path/filepath package</h3>
<p>
In Go 1, the <a href="/pkg/path/filepath/#Walk"><code>Walk</code></a> function of the
<code>path/filepath</code> package
has been changed to take a function value of type
<a href="/pkg/path/filepath/#WalkFunc"><code>WalkFunc</code></a>
instead of a <code>Visitor</code> interface value.
<code>WalkFunc</code> unifies the handling of both files and directories.
</p>
<pre>
type WalkFunc func(path string, info *os.FileInfo, err os.Error) os.Error
</pre>
<p>
The <code>WalkFunc</code> function will be called even for files or directories that could not be opened;
in such cases the error argument will describe the failure.
If a directory's contents are to be skipped,
the function should return the value <code>SkipDir</code>.

<em>Updating</em>:
The change simplifies most code but has subtle consequences, so affected programs
will need to be updated by hand.
The compiler will catch code using the old interface.
