Thanks for responses to my question about the need for global $var within a 
function whose parameter is &$var (unnecessary; function is operating 
directly on the original because of the &).

Now this raises another question.  Given the above, in those cases where a 
function is intended to operate on a global variable--and only those cases, 
why wouldn't you *always* define the parameter with & instead of using a 
global statement?
