The latter. I always considered type, require, pairs, table, string, io
part of the language or Lua libraries.

What I mean is I don't do this:

mycount = 3

function inccount()
	mycount = mycount + 1
end 

inccount()

Instead I typically do something like this:

local mycount = 3

function incc(number)
	return number + 1
end 

mycount = incc(mycount)

Also, I create and call functions globally. In most languages they're
not data, and I've had few if any problems from using functions
globally instead of passing them as arguments.
