How to call static methods in ColdFusion?

Adobe added support for static functions in ColdFusion. However, I can't find examples of how to use them neither on [official Adobe website](https://helpx.adobe.com/coldfusion/cfml-reference/coldfusion-tags/tags-f/cffunction.html) nor on [CFDocs](https://cfdocs.org/cffunction).

Traditionally you use functions by making instance of component and calling a function:

```
<cfset a = createObject("component", "a") />
<cfset a.test() />
```

Now, say I create a static function inside my `a` component:

```
<cffunction name="testStatic" access="public" modifier="static">
    ...
</cffunction>
```

How am I suppost to call it?

I can call it by making an instance like the old way:

```
<cfset a = createObject("component", "a") />
<cfset a.testStatic() />
```

but that defeats the point of making a function static.

[This SO answer](https://stackoverflow.com/questions/7288302/what-is-the-equivalent-of-static-methods-in-coldfusion#answer-70556156) shows how to use a component using script syntax which uses two columns `::`:

```
<cfscript>
    Cube::isValidModel( model )
</cfscript>
```

but it does not show how `Cube` component gets imported into `.cfm` file.
