I've thought that Org could do that, i.e., export some emacs highlighted
#+BEGIN_SRC...#+END_SRC block to LaTeX.  However, it just created a
verbatim environment and the docs suggest that there is also support for
lstlistings and minted but not "hand-crafted" LaTeX highlighting.  I've
used the latter several years ago, and have been very satisfied.  I have
no idea about LaTeX3 support, though.

Well, that's certainly feasible to some degree, i.e., you can access all
faces and their attributes and convert them to some similar looking
LaTeX code.

Maybe someone on the list wants to start hacking away.  To get started,
could you supply some language snippet in some language supported by
stock emacs -Q, a screenshot how it looks, and the equivalently looking
LaTeX code?

Well, that sounds like a very worthwhile goal indeed!
