Nearly my entire professional career has been spent using languages other than lisps, but I am not really sure what you mean by use of syntax telling a story.

Perhaps the subset of C++ used reveals something about the development team that wrote it I guess? But there are certainly analogous things in lisp. Is the code macro heavy or light? Was the developer trying to treat the language like an imperative language, or functional? Massive monolith functions, or many small almost mathematical functions? Comments, or no comments?

I think that C++ and Lisp might actually be relatively unique in that respect. You typically don't see much variety in Java (beyond "This code was clearly written by a C developer who wishes he could just use C for this", which comes through loud and clear sometimes), and even less in Python.
