Modernize code and improve readability

[XhmikosR]

This is an old patch I had lying around.

The size increase should be small, but I believe it makes code easier to read and also uses a few more modern features.

Converting to draft until the code on main is sorted after #446.

@addyosmani can you check the this PR and #403 and if everything looks good then cut a new minor version?

This is what we have so far: 3.0.1...main

@addyosmani friendly ping!

[addyosmani]

@XhmikosR Yes! Apologies as my bandwidth is low at the moment. Would you prefer I review and land 403 first, 444, or no preference?

[XhmikosR]

@addyosmani no worries! Better land/review this PR and I can rebase #403 later :)

@addyosmani friendly ping :)

Minor: CI tests appear failing for me. The changes overall look reasonable but just want to double check that bit :)

[XhmikosR]

These errors happen on main too, they are random and running CI again fixes them. Not sure why, but I never managed to pinpoint the root cause...

LGTM

Thanks again, @XhmikosR! 🥳
