How to make multiple shadow with Stylus?

Question

css

Hey! I saw this function on SASS (to make a starry sky):

// n is number of stars required
@function multiple-box-shadow ($n) 
  $value: '#{random(2000)}px #{random(2000)}px #FFF'
  @for $i from 2 through $n
    $value: '#{$value} , #{random(2000)}px #{random(2000)}px #FFF'

  @return unquote($value)

#stars{
    box-shadow: multiple-box-shadow(700)
}

I want to rewrite it for Stylus, but it doesn't work. Here's what I've tried:

random(min, max)
  return floor( math(0, "random") * max + min )

$coordinates = random(1, 2000)px 
$distortion = random(1, 20)px

// n is number of stars required
multiple-box-shadow($n)
  for $i in (1..$n)
    $value = $coordinates  $coordinates $distortion $distortion  #FFFFFF,
    return $value

#stars
    box-shadow multiple-box-shadow(700)

It turns out that random is not recalculated, the box-shadow value is added only once.
Here is a non-working example codepen.io/Kitana/pen/BNdpqv (but it's convenient to look at the compiled css right away)
Tell me how to fix it?
