I have the following macro that is working until 27.1.
(defmacro cl-concatenatef (type place &rest sequences)
`(cl-callf2 cl-concatenate ,type ,place ,@sequences))
cl-concatenate is inlinable (since forever) as declared in cl-macs:
(cl-proclaim '(inline cl-acons cl-map cl-concatenate cl-notany
cl-notevery cl-revappend cl-nreconc gethash))
In 27.1 after expansion only (apply #'seq-concatenate type sequences)
remains bypassing the cl-concatenate autoload which is supposed to load
the dependency seq.el.

What did that expand to in Emacs 26?

The body of cl-concatenate before Emacs 27:
(pcase type
(`vector (apply #'vconcat sequences))
(`string (apply #'concat sequences))
(`list (apply #'append (append sequences '(nil))))
(_ (error "Not a sequence type name: %S" type)))

Thanks. Then does the patch below fix the problem in Emacs 27.1?

But it seems the function will become slower when called regularly
because of the (require 'seq).
Is it better to remove cl-concatenate from the cl-proclaim list in
cl-macs.el?

Then I'd like to push this fix to the release branch, but...

...slightly, yes.

Wouldn't that make it even slower? And cause incompatibilities with
already byte-compiled files that saw the original cl-macs.el?
But I'm not an expert on these issues, so I'l defer to Stefan and Lars
here.

Hey, what did I do? :-)
I think the easiest fix here is to put an autoload cookie on
seq-concatenate. But there may be something off on the macro expansion
that should be fixed instead, perhaps?

Leo, does this work for your use case? In your opinion, is this
better than my suggestion?

Yes autoload works too.
I was hesitant to suggest it because the autoload (cookie) would live
too far away from cl-concatenate.

I didn't comment much on this point last night.
Adding (require 'seq) to cl-concatenate is probably the least favourable
because it also defeats the purpose of the `inline' cl-proclaim.
Adding autoload cookie for seq-concatenate is simple though not the
cleanest, IOW, we have the workings of cl-concatenate in some situations
depend on the autoload cookie. But this is not uncommon practice.
Given the dilemma we are in I wonder if the considerations for `inline'
cl-concatenate in the first place are no longer applicable.

Thanks.
Stefan, any comments? My personal tendency is to add the autoload
cookie, with a comment saying that cl-concatenate needs that. At
least on the emacs-27 branch. Any problems or issues with that? What
do people think about removing cl-concatenate from the inline
declaration (on master)?

I've now done both, and I'm closing this bug.
Thanks.

Indeed. But my suggestion to remove it was based on the fact that
cl-concatenate depends on another package at runtime, unlike other items
on that list.
