what do you think of this?

[Asko Kauppi <asko.kauppi@...>]

Insteead of the regular "_,_, str= string.find( "  I'm considering 
using the following functions:

	-----
	-- Useful when needing just a single return value (i.e. from 
'string.find()')
	--
	function first( ... ) return arg[1] end
	function second( ... ) return arg[2] end
	function third( ... ) return arg[3] end

This makes the code easier to read, and is not so obscure as the 
built-in '( )' notation
(that only extracts the first item anyhow).

What do you normally do - are there better ways to achive this?
