A useful example of `intersect` functionality is a "related posts" block. `isset` allows us to create a list of links to other posts that have tags that intersect with the tags in the current post.
The following is an example of a "related posts" [partial template][partials] that could be added to a [single page template][single]:
{{< code file="layouts/partials/related-posts.html" download="related-posts.html" >}}
<ul>
{{ $page_link := .Permalink }}
{{ $tags := .Params.tags }}
{{ range .Site.Pages }}
{{ $page := . }}
{{ $has_common_tags := intersect $tags .Params.tags | len | lt 0 }}
{{ if and $has_common_tags (ne $page_link $page.Permalink) }}
<li><a href="{{ $page.Permalink }}">{{ $page.Title }}</a></li>
{{ end }}
{{ end }}
</ul>
{{< /code >}}
