⚠️  ⚠️ Note for reviewers, hackers and fellow systems/low-level/compiler engineers ⚠️ ⚠️ 

If you have a lot of experience with this kind of shenanigans and want to improve the **first** version, **please make a PR against my branch** or **reach out by email** or **suggest code changes directly on GitHub**. 

If you have any **refinements or optimizations** please, wait until the first version is merged before starting hacking or proposing those so we can keep this PR productive.
