Ick, I posted again about this before I noticed you answer.

How strange... I've had this in emacs for ages:
(setq default-abbrev-mode t)
(read-abbrev-file)

It seems to work that way.  But when I tried replacing it with your
formulation, abbrevs are not turned on.

I thought that was what was turning on abbrevs in sh, c, perl etc.

Hmm, must have been some reason for it... But with that in there I
I guess the way is to set (setq cperl-electric-keywords t) then.

Maybe lots of people didn't like the electric features.  So turned off
by default. I remember seeing complaints about it.  I personally like
electic in cperl.

I found this in C-h m (in cperl mode):

[...]
CPerl mode provides expansion of the Perl control constructs:

   if, else, elsif, unless, while, until, continue, do,
   for, foreach, formy and foreachmy.

and POD directives (Disabled by default, see `cperl-electric-keywords'.)
[...]

So your answer got me straigntened out.... thanks.

I just tested with  (setq cperl-electric-keywords t)
in emacs, and sure enough, cperl-mode started with abbrevs turned on.

I see now that turning on perl-hairy also makes abbrev mode enabled
on open of perl file.
