Given that strict had created the __declared table inside _G I was able to make a function to list all globals like so:

function listglobals()
	local t = getmetatable(_G)
	for i,_ in pairs(t.__declared) do
		local ty = type(_G[i])
		local sz = 0
		if ty == 'table' then sz = #_G[i] end
		printf('%20s,	%10s,	%4d',i, ty, sz)
	end
end

Its remarkable how easy it is to do things like this in Lua.
