Assinging a variable with "!global !default" not working

[bonfish]

In sassmeister.com this

@function get-width() {
    $w: 10px !global !default;
    @return $w; 
}
a{
  width:get-width();
}

compiled with libsass 3.0.2 returns nothing.

gulp-sass 1.2.4 throws an error non-terminal statement or declaration must end with ';'

---

Setting $w: 10px !default !global; seems to work fine.
