Using Compass to generate normal and retina sprite maps
$sprites: sprite-map("sprites/*.png");
$sprites-retina: sprite-map("sprites-retina/*.png");
@mixin sprite-background($name) {
background-image: sprite-url($sprites);
background-position: sprite-position($sprites, $name);
background-repeat: no-repeat;
display: block;
height: image-height(sprite-file($sprites, $name));
width: image-width(sprite-file($sprites, $name));
@media (-webkit-min-device-pixel-ratio: 2), (-o-min-device-pixel-ratio: 3/2), (min-device-pixel-ratio: 2) {
// Workaround for https://gist.github.com/2140082
@if (sprite-position($sprites, $name) != sprite-position($sprites-retina, $name)) {
$ypos: round(nth(sprite-position($sprites-retina, $name), 2) / 2);
background-position: 0 $ypos;
}
// Hard coded width of the normal sprite image. There must be a smarter way to do this.
@include background-size(444px auto);
background-image: sprite-url($sprites-retina);
}
}
// Usage.
.mail-icon {
@include sprite-background(mail);
}

I believe i figured it out how to declare all the sprites in the map. Works well on top of whats above.

$sprite-names: sprite_names($icon-sprites);
@each $sprite in $sprite-names {
    .icon-#{$sprite} {
      @include icon-sprite($sprite, true);
    }
}
