By standard, you mean "CL", right?  If you want CL behavior, then do
(require 'cl), and it will then work.

Package: emacs
Version: 23.2+1-4
Severity: serious

The current definition of dolist in subr.el breaks lot of things that rely
on the standard 'dolist' behavior:

    $ emacs -Q --debug-init --batch --eval "(dolist (elt '(1 2)) (return elt))"
    Symbol's function definition is void: return

    $ macs -Q -l cl-macs --debug-init --batch --eval "(dolist (elt '(1 2)) (return elt))"
    <no errors>

Please update subr.el::dolist in respect to 'return'.
