// coverage is used by NewCoverage which is used as a convenient way for

// their own implementation, will not break if later new slice types are added.

Many plugins start as a script plugin coded in a build script.
This offers an easy way to rapidly prototype and experiment when building a plugin.
Let's take a look at an example:
