second order functions?

Hi all,

I was wondering how to define a second order function in maxima, i.e. a 
function returning a function.

More concrete: I want to define a function make_fn(n) which should return a 
function fn(x), where the way in which fn(x) is computed depends on the 
initially provided n.

I tried it as follows:

make_fn(n) := lambda([x],n+x)$
fn3: make_fn(3)

but this evaluates to lambda([x], x + n), whereas I want it to evaluate to 
lambda([x], x + 3)

Thanks, Joachim.
