Re that last: FWIW, in Emacs Lisp (which is case-preserving and mostly lowercase by convention, without the legacy symbol case behavior of CL), docstring convention is to use single quotes for most literals and to use all-caps to mean the value of a local symbol—usually a function argument, but sometimes a variable introduced in running text for describing the structure of data or such. Last I checked, CL wasn't as consistent across projects, but I tend to carry the Emacs convention there when not conforming to a different local style, and wonder sometimes who would have their monocle pop off to see it…
