[Chicken-users] newbie question - nth-value ?

[Joe Python]

When I try to call the builtin 'nth-value' , I was expecting a number, instead I am getting a error.

<snip>

#;1> (nth-value 2 '(2 3 4 5))

Error: (list-tail) out of range

((2 3 4 5))

</snip>

The documentation says ;

[syntax] (nth-value N EXP) 

Returns the Nth value (counting from zero) of the values returned by _expression_ EXP.

Did I interpret it wrong?
