Example
Variables can be used in string interpolation. This allows you to dynamically generate selectors, properties and values. And the syntax for doing so a variable is #{$variable}.
$className: widget;
$content: 'a widget';
$prop: content;
.#{$className}-class {
#{content}: 'This is #{$content}';
}
// Compiles to
.widget-class {
content: "This is a widget";
}
You cannot, however use it to dynamically generate names of mixins or functions.
