Then I should have tested the macro with `macroexpand-all' instead of `macroexpand'. However, I've tried using the macro, and it seemed to work, albeit it choked on the unquoted symbol passed to `fboundp'. > (funcall (symbol-function 'defun) 'foo nil) > does not seem to work either, which would mean that you can't save > `defun's definition. `defun' is not a function, it's a macro (defined in C source code). Thanks for answering.
