The reason why I do it is so I can turn on the debug switch by changing the value of the variable in one module
Which of course you could also do by using a lexical variable instead of a global one, plus providing a *function* which turns debugging on/off. The latter has the advantage that you could later hook in arbitrary actions to be executed when the debug state changes between on and off.
