Two symbols with the same symbol name (i.r.t. `equal') are not necessarily the same symbol (i.r.t `eq'). So (eq '## (make-symbol "")) ;=> nil even though they both have the same name, (equal (symbol-name '##) (symbol-name (make-symbol ""))) ;=> t which is why I don't think that the name "the empty symbol" makes sense. -- Philip Kaludercic
