RE: Function Addresses?

["Paul Hudson" <phudson@...>]

My guess (not having looked at the C implementation) is that it's probably
easier to create a new closure on each call than work out that there's no
need in this particular case.

In general, you do need a different closure on each call, of course.

function a()
	local i = 0;
	return function () i = i + 1; return i; end
end

Why would it be desired to have a new anonymous function created for
each call?

function a()
	return function () end
end

print(a())
print(a())
