Scope Coloring (not just syntax coloring)

Scope coloring was first suggested by Douglas Crockford. So far the only plugin for Sublime Text 2 (that I know of) that implements scope coloring has been made solely for JavaScript at https://github.com/mazurov/sublime-levels .

It would be great if this feature could be implemented for all languages, especially Clojure and Scheme (for me).

Difference between scope coloring and syntax highlighting:
