// ----
// Sass (v3.3.0.rc.1)
// Compass (v0.13.alpha.10)
// ----

// add this mixin to your Sass file:
@mixin ext($name, $silent: false)
  @if $silent == true
    @extend %#{$name} !optional
  @else
    @extend .#{$name} !optional
 
// then you may extend other classes in a shorter format:
 
.foo
  background: red
 
%almond
  border: pink 1px solid

.bar
  +ext(foo)
  +ext(almond, true)
  //instead of:
  //@extend .foo !optional
 
.joy
  +ext(almond, true)
