> Templeton, for example, noted that Common Lisp has no feature that corresponds to Emacs's buffer-local variables, which are often used in Emacs extensions. I don't know about that; it sounds very much like dynamic variables. It's usual in a Common Lisp implementation to give each thread its own set of dynamic variables (indeed, that's close to the only sane thing to do); I can't offhand see why it would make sense just to treat buffer-local variables similarly. But perhaps there're some semantics I'm not familiar with.
