Re: Read-Only Tables Patch

[Michael Grubb <lua@...>]

Another issue with this approach is list iteration:

	mytab = {}
	mt = { __index = someCfunction }
	setmetatable(mytab, mt)
	local i, v = next(mytab, nil)
	while i do
		print(i .. " : " .. v)
		i, v = next(mytab, i)
	end

The above will never print anything as 'mytab' is empty.
The other goal is transparency.  The patch provides this.

Thanks for the feedback,
