Totally right, for globals as Dirk mentiones them (sorry Dirk). That should teach me to formulate my question more precise.
So from my original post;

So I guess with a 'generic global' what I mean is to set some meta-data (eg. module._VERSION) or configuration options (eg. _TEST as per above).
Surely some of you must also be using constructs like this?
