I agree-- if you have a function that updates a number of global objects 
or variables, you don't want to force yourself to list them all as 
arguments every time you call the function.

As a further note, I always use global statements in order to make 
objects available to the local scope, but for looking at or updating 
regular variables I tend to use the $GLOBALS array so that the local 
namespace doesn't get to crowded.
