`cddr' and `caddr' are here (in subr.el or lisp/subr.el.gz),
but not "cadader".
In subr.el, lines 517-655, are
caar
cadr
cdar
cddr
caaar
caadr
cadar
caddr
cdaar
cdadr
cddar
cdddr
caaaar (from here on, the docstrings buttonize `car' and `cdr')
caaadr
caadar
caaddr
cadaar
cadadr
caddar
cadddr
cdaaar
cdaadr
cdadar
cdaddr
cddaar
cddadr
cdddar
cddddr
Also, what does this do?
(declare (compiler-macro internal--compiler-macro-cXXr))
They all have it. Still the definitions are normal Lisp?
`internal--compiler-macro-cXXr' (line 503) is as well, for
that matter (not a macro with `defmacro'.) What does that
mean? You get one version when you byte-compile and one when
you don't?
Also, it says (lines 500-502)
;; Note: `internal--compiler-macro-cXXr' was copied from
;; `-compiler-macro-cXXr' in macs.el. If you amend
;; either one, you may want to amend the other, too.
Why have the same thing in two places?
As for CL, there are, in Elisp
cl-caaar
cl-caadr
cl-cadar
cl-caddr
cl-cdaar
cl-cdadr
cl-cddar
cl-cdddr
cl-caaaar
cl-caaadr
cl-caadar
cl-caaddr
cl-cadaar
cl-cadadr
cl-caddar
cl-cadddr
cl-cdaaar
cl-cdaadr
cl-cdadar
cl-cdaddr
cl-cddaar
cl-cddadr
cl-cdddar
cl-cddddr
They are aliases tho, 24, the original were 28, this is
because these
caar
cadr
cdar
cddr
don't have any cl- aliases.
BTW the docstrings for aliases, e.g.
cl-caaaar is an alias for ‘caaaar’ in ‘cl-lib.el’.
is a little confusing, to mean it looks like `caaaar' is in
cl-lib.el - better
cl-caaaar is an alias in ‘cl-lib.el’, for ‘caaaar’.
or even better
cl-caaaar is an alias in ‘cl-lib.el’, for ‘caaaar‘ in ‘subr.el’.
