24.3.50; cperl-mode: autohelp not working

1. C-x C-f somefile.pl
2. M-x cperl-mode
3. Put your cursor on some keyword - say `return'.
4. C-c C-h v

   See the following in the echo area.

   return(LIST)

5. Turn autohelp on.  M-x cperl-toggle-autohelp 

   Wait.  Wait.  Keep waiting.  Nothing happens.

That turns it off, as indicated by the message "Perl help messages will
not be automatically shown now.".

I've never used cperl-mode, but:

C-h f cperl-toggle-autohelp

  -> Delay of auto-help controlled by `cperl-lazy-help-time'.

C-h v cperl-lazy-help-time

   -> Its value is nil.
   *Not-nil (and non-null) means to show lazy help after given idle time.

Seems like a dumb default, but there you go. So

emacs -Q --eval '(setq cperl-lazy-help-time 1)'

seems to work fine.

Glenn

I don't see any changes to cperl-mode.el (as of rev 115070).  I cannot
quite agree how this can be "notabug".  Dumb defaults are bugs in my
opinion.  Either fix the bug or leave the bug open.
