Actually, I meant "alternative" as in "a format for specifying alternative 
return values". For example:

function foo( a )
	if type(a) == 'string' then
		return a, string.len
		return nil, 'not a string'

What types of values does this function return? I want to either say that it 
returns "a string and a number" or "nil and a string" OR that the first value 
is "a string or nil" and the second "a number or string". Conditional return 
values, etc. So I need some kind of intuitive markup for that, e.g.:

--: (string|nil) the string itself, or nil if a was not a string
--: (number|string) the length of string a, or an error message if it 
--- was not a string

...something like that. Maybe

--: if parameter a is a string
--: (string) the string itself
--: (number) its length
--: if the parameter is not a string
--: (nil) nil value
--: (string) error message

Ack. But that's way too big, although pretty easy to parse.

I did like to check the reference out, thanks a lot for that. I've been 
looking into simple markups recently, and it was very nice to find out about 
reST. My main problem with it is its dependance on indentation (not an issue 
for the Python people, of course >: ) ), which makes it unfit for some of my 
purposes, but other than that is pretty nice.

Nah. They're not that complicated. >; )

Thanks for the input,
