Trying it without being on a hook was a good idea.  I found this was
the appropriate syntax:

(local-set-key (kbd "TAB") 'indent-or-complete)

Instead of doing it manually each time I edit something in cperl-mode,
I'd like it to be done automatically.

Based on my understanding, I should do something like this, right?

(add-hook 'cperl-mode-hook
          (function (lambda ()
                      (local-set-key (kbd "TAB") 'indent-or-complete)
                      )))

Yet, when I do describe-key & hit tab, this is what I get:

TAB runs the command cperl-indent-command
   which is an interactive compiled Lisp function in `cperl-mode'.
(cperl-indent-command &optional WHOLE-EXP)

Any advice on things to try next?

Thanks,

Are you sure you're using cperl-mode?
