-/**
- * CSS @import node
- *
- * The general strategy here is that we don't want to wait
- * for the parsing to be completed, before we start importing
- * the file. That's because in the context of a browser,
- * most of the time will be spent waiting for the server to respond.
- *
- * On creation, we push the import path to our import queue, though
- * `import,push`, we also pass it a callback, which it'll call once
- * the file has been fetched, and parsed.
- *
- * @package Less
- * @subpackage tree
