Support for :root variables?

[FalkoJoseph]

@define-mixin column-generator {
    @for $i from 1 to calc(var(--columns) - 1) {
         &.with-$(i)col {
           width: (var(--one-column) * 1)px;
        }
    }
}

@for $i from 1 to calc(var(--columns) - 1) doesn't work. Anyone who knows why?

Is there a possibility to use the CSS4 variable spec alongside of simple-vars? Would be nice to stay as close to the CSS4 specs as possible. And this might solve the problem to use them as iterators.

@FalkoJoseph I believe that the current version of postcss-calc is supposed to work in the CSS properties but not in the at-rules.

Okay thanks for the update 👍
