Agreed. The more global items you have the more dependancies you create between
files. And the more dependancies the harder it is to change things without
upsetting something (or someone) else.

A good rule of thumb (and this has been around since the 1970s) is eliminate
every instance of module coupling, except where you absolutely must have for
performance reasons (and that is almost never).

This doesn't really apply to global constants though.
