Reading code can be a valuable learning rescource.
Is there any particular source code you have read, that taught you a lot of things? (Preferably but not nescessarily Lua)
If so, this is the place to share it!
When you post links to code, please tell us why you think it's good (or bad) and what can be learned from it.
This is a really good idea for a topic! Unfortunately, I'm not sure that I have much to add but I look forward to people hopefully posting some examples. One of the thing I like about Love is being able to pick through peoples' code and see how they did things; I've found it's the best way for me to learn.
This book is really heavy stuff but its probably the best programming book ive read.
As a warning its pretty abstract, uses scheme and is written for MIT students.
The lua code I learned the most from might have been rxi's flux library. It was totally outside of my normal way of thinking, and you know it's good because it's short, readable, and works flawlessly.
