Sass @each with multiple variables

I'm just getting started with Sass and Compass, and I'm loving it. Something I'd like to do is take advantage of the @each function to simplify repetitive tasks. However, I've only seen examples of @each inserting one variable, and I'd like to be able to use multiple variables.

The standard way (from the Sass Reference):

@each $animal in puma, sea-slug, egret, salamander {
  .#{$animal}-icon {
    background-image: url('/images/#{$animal}.png');
  }
}

Which is great, but I'd like to be able to do something like:

@each {$animal $color} in {puma black}, {sea-slug green}, {egret brown}, {salamander red} {
  .#{$animal}-icon {
    background-color: #{$color};
  }
}

Is this possible?
