Hello,

Not sure whether this has been reported (or whether it's not supposed to work by design) but the following:

@function testfunc($x) {
    @return $x;
}

body {
    --test: testfunc(42);
    -test: testfunc(42);
    test: testfunc(42);
}

Turns into the following CSS:

body {
    --test: testfunc(42);
    -test: 42;
    test: 42;
}

Is there any reason why the CSS variable one does not work?
