For what it's worth the perl-mode (in Emacs-CVS at least) seems to highlight
them correctly.

But it does not turn cperl-mode to highlight them properly :-)
Also, it seems that cperl-mode on XEmacs (with a lower version
of Cperl-mode) does not have such a problem.

Speaking of perl-mode, Richard told me that this mode is obsolete
and shall be deprecated. What's his status? (we have a bunch of
bug reports in the Debian BTS about it).

Huh?  It's the default perl-mode, and it's the one I've been using (and
improving) for the last few years.  Try it (in its Emacs-CVS version) and
pass on the bug-reports.

I know it and I've used it until Richard told be it was obsolete.
I know it doesn't have such problems, at least for highlighting. I'll forward
bug reports then.

Should the I contact the cperl-mode maintainer directly about the current
bug? Does he read the emacs lists?

How about stealing/modifying the following from cperl-mode so
outline-minor-mode works in perl-mode?

(defvar cperl-outline-regexp
  (concat cperl-imenu--function-name-regexp-perl "\\|" "\\`"))
(make-local-variable 'outline-regexp)
(setq outline-regexp cperl-outline-regexp)
(make-local-variable 'outline-level)
(setq outline-level 'cperl-outline-level)
;; Suggested by Mark A. Hershberger
(defun cperl-outline-level ()
  (looking-at outline-regexp)
  (cond ((not (match-beginning 1)) 0)	; beginning-of-file
	((match-beginning 2)
	 (if (eq (char-after (match-beginning 2)) ?p)
	     0				; package
	   1))				; sub
	((match-beginning 5)
	 (if (eq (char-after (match-beginning 5)) ?1)
	     1				; head1
	   2))				; head2
	(t 3)))

    Speaking of perl-mode, Richard told me that this mode is obsolete
    and shall be deprecated.

I hoped that CPerl mode would always be better than Perl mode, but
that turned out not to be the case (not yet).  And the author of CPerl
mode lost interested in maintaining it.  So unless someone else takes
it over and fixes the problems, we cannot consider Perl mode obsolete.

Hi,
I use GNU Emacs 21.3.1 (i386-mingw-nt5.1.2600). The highlighting
issues were true for 4.23 cperl-mode which was the version I've had
to date. Now I have cperl 5.0 and the mentioned bug (and others) is gone. 
But
this newest cperl version is not included in emacs distribution
(even in 21.4.2).

I'm surprised. I could reproduce the bug with a recent CVS trunk.
I'll have a closer look.

Thanks.

Re: Cperl-mode does not highlight function names properly

[Richard Stallman]

It would be nice for someone to work on installing the latest cperl
mode.  The author of cperl mode does not seem to want to do it,
but I would be glad if he did.

Hi,

Cperl-mode does not highlight properly function names that contain
Perl keywords.

Here is a test case.

------------

#!/usr/bin/perl

sub test_read_file ()
  {

  }

sub func ()
  {

  }

------------

You will notice that 'read' in test_read_file is highlighted as
a keyword whereas 'func' is hightlighted as a function name.

I could reproduce the problem with current CVS trunk as well.
