Seemingly inconsistency between function in a local variable and local function

[Robert Klemme <shortcutter@...>]

Hi,

while musing about http://forum.luahub.com/index.php?topic=3559.0 I
ran across this:

do
--[[ all these do NOT work
	local f2
	local f2 = nil
	local function f2() end
--]]

	local function f1()
		return f2()
	end

	local function f2()
		return 123
	end

	function f()
		return f1()
	end
end

ok, error = pcall(function() print(f()) end)

if ok then
	print('--OK')
else
	print(error)
end

do
	-- this works:
	local g2

	local function g1()
		return g2()
	end

	--[[
	but we cannot do
	local function g2()

	only if assigned like this:
	--]]
	g2 = function()
		return 123
	end

	function g()
		return g1()
	end
end

ok, error = pcall(function() print(g()) end)

if ok then
	print('--OK')
else
	print(error)
end

Why is that?  What did I overlook?

Kind regards

robert
