The error was not thrown by the buffer-local-value function. It was thrown by eval, trying to (recursively) evaluate the fundamental-mode form, whose result it would then pass as the first argument buffer-local-value. > (local-variable-if-set-p 'major-mode) => t > (eq major-mode 'fundamental-mode) => t > (equal major-mode 'fundamental-mode) => t > (symbol-value 'major-mode) => fundamental-mode > (assoc-default 'major-mode (buffer-local-variables)) => fundamental-mode You have demonstrated that the major-mode symbol has its value cell set to the fundamental-mode symbol, and several other facts about the major-mode symbol. You have not demonstrated any facts about the fundamental-mode symbol. -- Kevin Rodgers Denver, Colorado, USA
