I see the same thing that I see when I use this: (insert (propertize "hello" 'face '(:height 10.0))) That second sexp follows the description (doc) of `propertize'. The first sexp does not. The bug, IMO, is that this is not "a sequence of PROPERY VALUE pairs...", which is what the doc says it should be: (quote (quote '(:height 10.0)))=20 I wouldn't think of this as a doc bug because (1) this behavior is so unusual, and (2) I see no reason for it - no advantage in any way. Wrt #1: nowhere else, AFAIK, do we accept (quote (quote (quote SEXP))) or (quote (quote (quote (quote (quote SEXP))))) or as a substitute for SEXP. Those sexps are certainly are not equivalent for `eval'. We don't do that anywhere else, and I don't see why we should do it here (or anywhere)? I asked whether there's some special reason we should. You've said, I think, that you too see no reason why this is done, except the possible historical one of it having just happened by "accident". That's not a good reason for keeping this exceptional (I'd say bugged) behavior, IMO. That's all.
