Get value of another element

#sidebar {
    float: left;
    width: 300px;
}

#container {
    margin-left: #sidebar.width;
}

Is it possible something like this to be implemented in sass?

Just thought I’d chime in. I heard Stylus does this…

So, I was kind of wrong about Stylus. See: http://stylus-lang.com/docs/variables.html#property-lookup

You can reference the property of a parent selector, but it must be a parent or the same selector - if I’m reading the docs right.
