_old_get_function.scss

@function get($dict, $key, $default: false) {
    /* a python-style "get" function to emulate dictionary access in scss
        param: $dict the dict you'd like to 'get' from
        param: $key the 'key' to access
        param: $default a default value to return should the 'get' fail

        see:

        example:
            // define a scss 'dictionary'
            // note: 'key values' are seperated by a space ONLY
            // note: 'key value' paris are separated by a comma
            $colors :
              white #fff,
              black #000,
              red #ff0000;

            .foo {
                color: get($colors, white);
            }
            .bar {
                color: get($colors, missing-color, $default: #00ff00);
            }
    */

    @each $item in $dict {

        $index: index($item, $key);

        @if $index {
            $return: if($index == 1, 2, $index);
            @return nth($item, $return);
        }
    }

    @return $default;
}

This has been replaced by maps, and map functions in SCSS; but I wanted to put this somewhere.
