I would appreciate any feedback or comments on it.
Thanks and best regards,

My thoughts, mostly nitpicks:
> Penlight is a clear example of a function that doesn’t follow this rule. It is a big library that does many different things.
I don't think Penlight is a function.
> Names with more than 1 word are neither under_scored nor CamelCased (for example, getmetatable).
This has been the subject of holy wars since programming languages were invented. I personally prefer camelCase, but I also have a bad habit of not being consistent about it.
> I also recommend adding _VERSION, _DESCRIPTION, _LICENSE & _URL fields to all modules
This is another one of those things which I think doesn't have a real standard. My personal favourite method is something like:
mymodule._info = { name = "MyModule", description = "Does a thing with the stuff", homepage = "http://example.com/MyModule",
authors = { "Rena <hyperhacker@gmail.com>", "Tom <tom@example.net>", "Dick <chunkylover52@aol.com",
"Harry <webmaster@bees.net>", }, copyright = "2014 Rena Kunisaki", license = "MIT <http://opensource.org/licenses/MIT>",
version = "1.2.3.4", } but there's definitely merit to using just mymodule._VERSION and the like as well.

I like this, might have to steal it. ;-)
> State is a general programming term that can be think intuitively as internal memory.
Another sentence that could use some grammar touchup. (think -> thought of?)
> Instances leave in the aplication’s memory
Should be "live in" and "application's". "derivate" shortly after should be "derivative".
> This is partly due to some design decisions in the Lua.
Which Lua?
> We can, however, use something: the _expression_ (...), when evaluated at the top of a module, returns the “path” used to require it.
Interesting. I've never seen this. Is it documented somewhere?

Booooo. Remember when HTML, without scripts, was able to display text and even input fields, all on its own?
