Sass: Mixin to assign the same value to multiple properties at once

same-value.scss

@mixin same($values...) {
  $length: length($values);
  $value: nth($values, $length);

  @for $i from 1 to $length {
    #{nth($values, $i)}: $value;
  }
}

// Usage:
footer {
  @include same(top, left, right, bottom, 0);
  @include same(height, line-height, 60px);
}

// Output
footer {
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  height: 60px;
  line-height: 60px;
}

Show, velho! :)
