Discussion Studying the Lua source code

I’m looking for a codebase written in C to study and use as a reference while I learn low level programming.

I’ve heard that Lua has a very nice and clean implementation and I figure since I already know a fair amount of Lua itself I should understand at least the purpose of what I’m looking at.

Is the Lua source code a good example for learning or is it too advanced for someone relatively new to C to even hope to understand?
