The new function
<a href="/pkg/path/filepath/WalkDir"><code>WalkDir</code></a>
is similar to
<a href="/pkg/path/filepath/Walk"><code>Walk</code></a>,
but is typically more efficient.
The function passed to <code>WalkDir</code> receives a
<a href="/pkg/io/fs/#DirEntry"><code>fs.DirEntry</code></a>
instead of a
<a href="/pkg/io/fs/#FileInfo"><code>fs.FileInfo</code></a>.
(To clarify for those who recall the <code>Walk</code> function
as taking an <a href="/pkg/os/#FileInfo"><code>os.FileInfo</code></a>,
<code>os.FileInfo</code> is now an alias for <code>fs.FileInfo</code>.)
