  I do the following:

	do
	  -- code goes here
	end

for locals that I know I don't want hanging around.  Usually, it's for stuff
like:

	local data

	do
	  local f = io.open("datafile","r")
	  data = f:read("*a")
	  f:close() -- don't really need this, but I like being explicit
	end

	-- code that uses data
