1	+	Let's write a program that computers the fibonacci sequence. First we must define the base cases of the function. for the sake of simplicity, n <= 0 returns zero.
2	+
3	+	The base case for n <= 0:
4	+	if n <= 0 then
5	+	return 0
6	+	end
7	+
8	+	The base case for 1:
9	+	if n == 1 then
10	+	return 1
11	+	end
12	+
13	+	Now for a recursive case. For this implementation, we will stick with the original formula rather than optimizing it.
14	+
15	+	The recursive case for the fibonacci sequence:
16	+	return fib(n - 1) + fib(n - 2)
17	+
18	+	Finally, lets assemble this into a Lua function.
19	+
20	+	The fibonacci function:
21	+	local function fib(n)
22	+	@ The base case for n <= 0
23	+	@ The base case for 1
24	+	@ The recursive case for the fibonacci sequence
25	+	end
26	+
27	+	our program:
28	+	@ The fibonacci function
29	+	print(fib(10))

32	+	compile
