Recent Elisp changes have rather gone the other way (adding a # rather

different semantics to '(lambda ...) and #'(lambda ...), other part is
that cl-flet and cl-labels also give different semantics to 'foo and

that you spelled the function correctly (and warn you if that function
is not known to exist).
