Add @extend Sass directive ?

[MinerCrafter]

Hello,

Sass offer a practical directive: @extend.

http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#extend

Example :

.error {
  border: 1px #f00;
  background: #fdd;
}
.error.intrusion {
  font-size: 1.3em;
  font-weight: bold;
}
.badError {
  @extend .error;
  border-width: 3px;
}

Result :

.error, .badError {
  border: 1px #f00;
  background: #fdd;
}
.error.intrusion,
.badError.intrusion {
  font-size: 1.3em;
  font-weight: bold;
}
.badError {
  border-width: 3px;
}

I use Twitter Bootstrap. I try to not edit his source code, i add my Less code after Bootstrap's code.
the @extend directive can be usefull to avoid code duplication !

What do you think about this ?

(Sorry, but i don't speak english very well).
