Those are not special forms like "defun", or even "if", but instead :foreground, :bold, anything that starts with a colon. `boundp' will always eval to t for those, as they are bound to their names. Perhaps it makes sense to exclude those, as those aren't variables, for sure. But this is possible (defvar :var-looks-like-keyword) though further assignment is not (?). So I don't think I'll add that. It doesn't hurt to have it say that :bold is :bold. -- Emanuel Berg, programmer-for-rent.
