Sass 3.3 (released on 2014/03/07) now allows you to use maps :
@include font-face('Entypo', font-files('entypo.woff'));
.icon {
display: inline;
font: 400 40px/40px Entypo;
}
$icons: (
star: "\2605",
lightning: "\26A1"
);
@each $key, $value in $icons {
.icon-#{$key} {
@extend .icon;
&:after {
content: $value;
}
}
}
