The elements supported are strings, integers and floats, although only float64 will match as expected.

In addition, `in` can also check if a substring exists in a string.

```
{{ if in .Params.tags "Git" }}Follow me on GitHub!{{ end }}
```


```
{{ if in "this string contains a substring" "substring" }}Substring found!{{ end }}
```
