FWIW, replacing `apply` with `eval` is not an "Improve"ment in my
book :-) It means now that `key-val-alist` contains code represented as
data (i.e. code to which flymake, the compiler, the eager macroexpander,
etc... don't have access) whereas it previously only contains values
(which can't contain code that needs macroexpansion, for example).
