Which CSS preprocessors support map at an arbitrary location in CSS?

Question

Which CSS preprocessors allow you to use loops (preferably maps in general) in arbitrary places in CSS, for example, in native CSS functions?
Let's say this:

background: linear-gradient(90deg, @map (hsl(60 * x % 360, 100%, 50%) 100% / 6 * x) 0 .. 6);

unfolded into the following:

background: linear-gradient(90deg,
    hsl(0, 100%, 50%) 0%,
    hsl(60, 100%, 50%) 16.6666666666667%,
    hsl(120, 100%, 50%) 33.3333333333333%,
    hsl(180, 100%, 50%) 50%,
    hsl(240, 100%, 50%) 66.6666666666667%,
    hsl(300, 100%, 50%) 83.3333333333333%,
    hsl(0, 100%, 50%) 100%
  )
/* сгенерировано:
print qq(
  background: linear-gradient(90deg,
    @{[(join ",\n    ", map {qq(hsl(@{[60 * $_ % 360]}, 100%, 50%) @{[100 / 6 * $_]}%)} 0 .. 6)]}
  )
)
*/

Does PostCSS allow this possibility?
