Part of the reason is that lexical-binding gives different semantics to '(lambda ...) and #'(lambda ...), other part is that cl-flet and cl-labels also give different semantics to 'foo and #'foo. Finally, if you keep the # part, the byte-compiler will be able to check that you spelled the function correctly (and warn you if that function is not known to exist). Stefan
