Coffeescript - loop only if array exists

Question

I want to iterate over array only if it exists.
Can this be a one-liner?

if array
    doSmth() for i in array

hha! I've just discovered that I can do this

if array then doSmth() for i in array

And also this

if array then for i in array
        foo = 1
        bar = 2
        baz = 3

So simple...

For a short loop like that I think the postfix-if would be more idiomatic:

doSmth() for i in array if array
