We have an issue where a local variable will be consumed by the doc generation and given a public entry into our API.md.

This was the case for the local variable (that was not exported out of the module) _usePrometheusPoll (with the underscore).

We should be able to create local variables and not have them generated in the documentation when we run the script.
