You can use closures for this.

local function f_maker()
	local foo = 1
	local bar = 2
	local baz = 3
	return function(a, b, c)
		foo = foo + a
		bar = bar + b
		baz = baz + c
		return foo + bar + baz
	end
end
f = f_maker()

f is now a global function with three items of static data (in C parlance).

Does that help?
