Emacs syntax highlight of nested backquote forms in lisp buffers

Question

Is there a package for it? If not, what should I look into to create a package for it?

This package should highlight levels of parts of a nested backquote form in different colors.

`(a :i-am-in-level-1
    `(a :i-in-level-2
        ,(a :level-1 `(a :level-2))
        ,',(a :level-0)))

For example, level 0 should have no highlight, level 1 might have a light grey background, level 2 is in a darker background, and so on.

sounds like a bit of an overkill, `show-paren-mode` is more than enough for me — abo-abo, Aug 20 '13 at 12:53
show-paren-mode is for parens management which is orthogonal to the problem of highlighting quote/unquote levels. — Jisang Yoo, Aug 20 '13 at 13:35
If you do come up with some code that does it, please consider submitting it for inclusion in Emacs or GNU ELPA. I'd welcome such a feature. — Stefan, Aug 21 '13 at 16:28

The rainbow-delimiters package does something similar for parens. You might take inspiration from there.

Just finished reading its code and tricks in its code can be adapted to all kinds of nested highlighting. – Jisang Yoo Aug 21 '13 at 10:50
