And for Lua 5.1:

(I personally don’t use patches like this because “Lua 5.1” is something pretty standardized with a bunch of different implementations; e.g. I wrote my Lua book with a C# developer who was using the moonsharp Lua implementation)

Seems like a no brainer that would help bring in more revenue too, it'd also be an "evergreen" book as new others can contribute over time.

I can't be the only one that would immediately buy a copy. :D

None of these are published because the popular ones are better and provide more functionality, but I want to share what I believe is more valuable: what I learned while writing them.
