* lisp/emacs-lisp/pp.el (pp--format-definition): Ensure that what we try
to print as a list of bindings has an appropriate format. This avoids
raising an error for SEXPs like (let X Y) inside `pcase' forms where our
heuristic expects a binding list in the X position.
This fixes an aspect of Bug#70868.
* lisp/emacs-lisp/pp.el (pp--insert-lisp): Print characters with
`prin1-char'. In all other cases consistently print with `prin1'.
`rm lisp/emacs-lisp/cl-preloaded.elc src/bootstrap-emacs`
followed by `make` ended up loading right after defining
`built-in-class-p` but before actually defining the
built-in-classes so the computation of bitsets failed.
* lisp/emacs-lisp/vtable.el (vtable-insert-object): Rename
argument AFTER-OBJECT to LOCATION; allow use of index to
refer to the insertion position; add argument BEFORE.
(Bug#70664).

change.

(compile_function): Set 'comp.func_safety'.
* lisp/emacs-lisp/cl-seq.el (cl-sort):
Don't use string mutation when sorting the characters in a string.
This avoids O(n^2) run time and makes it future-safe.
This fixes cl-substitute, cl-substitute-if, cl-substitute-if-not,
cl-nsubstitute, cl-nsubstitute-if and cl-nsubstitute-if-not,

re-search-backward before help-xref-button fail early, as that would
indicate a logic bug, and the backtrace would more accurately point
to the actual source of the mistake.
It has been effectively obsolete since Emacs 27, when the modern

Change `function` so that when evaluating #'(lambda ...)
we return an object of type `interpreted-function` rather than
a list starting with one of `lambda` or `closure`.
The new type reuses the existing PVEC_CLOSURE (nee PVEC_COMPILED)
tag and tries to align the corresponding elements:
- the arglist, the docstring, and the interactive-form go in the
same slots as for byte-code functions.
- the body of the function goes in the slot used for the bytecode string.
- the lexical context goes in the slot used for the constants of
bytecoded functions.
The first point above means that `help-function-arglist`,
`documentation`, and `interactive-form`s don't need to
distinguish interpreted and bytecode functions any more.
Main benefits of the change:
- We can now reliably distinguish a list from a function value.
- `cl-defmethod` can dispatch on `interactive-function` and `closure`.
Dispatch on `function` also works now for interpreted functions but still
won't work for functions represented as lists or as symbols, of course.
- Function values are now self-evaluating. That was alrready the case
when byte-compiled, but not when interpreted since
(eval '(closure ...)) signals a void-function error.
That also avoids false-positive warnings about "don't quote your lambdas"
when doing things like `(mapcar ',func ...)`.
