Because, most often it works like this, `setq' sets the default/global value if that is set, but the _local_ if that or both are set, and if neither are, it sets the default - unless the variable is defined with DEFVAR_PER_BUFFER in C or `make-local-variable' in Elisp, that means it "Automatically becomes buffer-local when set" so then setq will be like `setq-local' and not `setq-default' all tho none are set. Phew! Yes, most often ... but not always? ; don't use `setq' here, @#$&%! (setq-local lexical-binding nil) ; because `lexical-binding' is dynamic/special, i.e. the variable itself (special-variable-p 'lexical-binding) ; this function relies on a dynamic and/or special variable `n' (defun use-var () n) ; formal parameters are dynamic under dynabound (defun lexfun (n) (setq n 1) (special-variable-p 'n) ; but not special since they are not global (use-var) ) ;; (lexfun 2) ; 1 (special-variable-p 'n) ; nil -- underground experts united https://dataswamp.org/~incal
