clear_assign_all() -- deprecate?

Hi all.

I was wondering if anyone uses clear_assign_all() as it looks like it
can be deprecated if clear_assign() is modified to implicitly perform
the task of clear_assign_all() when no paramaters are given. Perhaps as
follows:

    function clear_assign($tpl_var=array())
    {
        if (is_array($tpl_var) && !empty($tpl_var)) {
            foreach ($tpl_var as $curr_var)
                unset($this->_tpl_vars[$curr_var]);
        } elseif (empty($tpl_var)) {
            unset($this->_tpl_vars[$tpl_var]);
        } else {
            unset($this->_tpl_vars[$tpl_var]);
        }
    }

One less function point.
