Then it would have to be called with `funcall' or `eval', which seems unlikely. I suppose it could also be the case that the "real" '< got uninterned, and then any Lisp read after that would generate a new '< that had no function. (Any Lisp already read would still use the old symbol, of course, even through `eval' and such.) Lennart, you can use functions like these to test for these cases: ;; Non-nil if sym is in the obarray OB (or `obarray'). (defun internp (sym &optional ob) (if sym (intern-soft sym ob) t)) ;; Non-nil if sym is the '< that was current when this function was read. (defun
