Is it possible to write a function in one line?

Question

CoffeeScript

Hello.
The question is more theoretical than practical.
Let's say in JavaScript setInterval with console.log:

setInterval(function() {
    console.log("test");
}, 1000);

The same code, but in CoffeeScript:

setInterval ->
    console.log "test"
, 1000

The same code in JavaScript, but in one line:

setInterval(function() {console.log("test");}, 1000);

And finally, the question:
How to implement this in one line in CoffeeScript, and in general, is it possible?
