/**

* This is an arbitrary example (overly complex with types for overly simplified kernel) to show type inheritance

* throughout the kernel's usage.

*

* The whole idea here is that you can define custom:

* - `constants`

* - `this` context

* - mapped kernels

* - arguments

* - kernel output
