If you are interested, I made a exception module for lua 5.1
To use it :
	require("exception").install()

then you can use :
	raise(exception_id, message)
	try(function()
		-- some code that may raise exceptions
	end, function(e)
		if e.error == exception_id then
			-- do something
			return true
		end
		return false -- the exception continues
	end

It's here:
