Trying some ideas for prefix solution

prefixed.css

h1 {
  -webkit-border-radius: 10px;
  -moz-border-radius: 10px;
  -ms-border-radius: 10px;
  -o-border-radius: 10px;
  border-radius: 10px;
}

body {
  background-image: -webkit-gradient(linear, #000, #fff), url('image.png');
  background-image: -webkit-linear-gradient(#000, #fff), url('image.png');
  background-image: -moz-linear-gradient(#000, #fff), url('image.png');
  background-image: -ms-linear-gradient(#000, #fff), url('image.png');
  background-image: -o-linear-gradient(#000, #fff), url('image.png');
  background-image: linear-gradient(#000, #fff), url('image.png');
}


body {
  display: -webkit-flexbox;
  display: -moz-flexbox;
  display: -ms-flexbox;
  display: -o-flexbox;
}

prefixed.scss

h1 {
  @prefixed(border-radius: 10px);
}

body {
 @prefixed(background-image: linear-gradient(#000, #fff), url('image.png'));
}

//Ambitious
body {
  @prefixed(display: flexbox, ($official: false, $oldwebkit: false));
}

Essentially trying to find a less unwieldy solution to setting prefixes!
