1.0.0 had a NORMALIZATION argument that controls how the function is
to be applied to its arguments, defaulting to #'APPLY. This is now
called CALL-NORMALIZER, but with the original :NORMALIZATION initarg
preserved since it is used by LISP-INTERFACE-LIBRARY.
What 1.1.0 called NORMALIZATION is now called :ARGUMENT-NORMALIZER.
1.2.0 and 1.0.0 are thus incompatible with the short-lived 1.1.0.
1.2.0 is backward-compatible with 1.0.0.
