Or an addition to cl-loop that would allow doing something like

do ...)
Then you could easily 'collect m' to get the list of matches if you want
that.
Your proposals looks nice to me ;-)
(Caveat: I have not been following this thread.)
I think that `cl-loop' should be as close to Common Lisp `loop'
as we can reasonably make it. We should _not_ be adding other
features to it or changing its behavior away from what it is
supposedly emulating.
If you want, create a _different_ macro that is Emacs-specific,
with whatever behavior you want. Call it whatever you want
that will not be confused with Common Lisp emulation.
Please keep `cl-' for Common Lisp emulation. We've already
seen more than enough tampering with this - people adding
their favorite thing to the `cl-' namespace. Not good.
Drew, i respect your opinion; but so far the change
would just extend `cl-loop' which as you noticed has being already
extended before.
For instance, we have:
cl-loop for x being the overlays/buffers ...
Don't see a problem to have those things. We already point out in the
manual that these are Emacs specific things, so nobody should be fooled
with that. As far as we cover all CL clauses, what problem could be in
having a few more?
I find interesting be able to do things like the following:
--8<-----------------------------cut here---------------start------------->8---
(require 'find-lisp)
(let ((op "defun")
(dir (expand-file-name "lisp" source-directory)))
(setq funcs
(cl-loop for f in (find-lisp-find-files dir "\.el\\'") nconc
(with-temp-buffer
(insert-file-contents-literally f)
(let ((regexp (format "^(%s \\(\\S +\\)" op)))
(cl-loop for x the matches of regexp using '(group 1)
collect x)))))
(length funcs))
=> 38898 ; op: defun
=> 1256 ; op: defmacro
=> 1542 ; op: defsubst
--8<-----------------------------cut here---------------end--------------->8---
