How to create multiple box-shadows in a Stylus function - css

Question

I found a SASS function for "starry sci" creating:
// 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 translate it to Stylus, but something doesn't work. I try:
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)
random function run only ones and the box-shadow value add only once...
Can anybody help?

Something like:
random(min, max)
return floor(math(0, 'random') * max + min)
multiple-box-shadow($n)
$value = '%spx %spx #FFF' % (random(1, 2000) random(1, 2000))
for $i in 2..$n
$value += ', %spx %spx #FFF' % (random(1, 2000) random(1, 2000))
return unquote($value)
#stars
box-shadow: multiple-box-shadow(700)

Answer 2

My colleague suggested this solution to me:
random(min, max)
return floor( math(0, "random") * max + min )
// n is number of stars required
multiple-box-shadow($n)
$coordinates = random(1, 2000)px
$distortion = random(1, 20)px
$value = $coordinates $coordinates $distortion $distortion #FFFFFF
for $i in (2..$n)
$coordinates = random(1, 2000)px
$distortion = random(1, 20)px
$value = $value, $coordinates $coordinates $distortion $distortion #FFFFFF
return $value
