If you want to have the logger be global, add 'shared' to both
the logger and the static this.
This initializes the data before main() is run, so there is no
need for singletons.
The added bonus here is that you can't accidentally log stuff
when debug(logging) isn't enabled, as the variable will not
exist.

Ahh, that is a much cleaner way to do it rather than using a
singleton.
By 'module level', I assume you mean in the module that defines
the Logger class? An 'import debug.logger' or somesuch would then
give all relevant modules access, correct?
Is the compiler smart enough to compile out all the symbols
associated with the logger if it is never instantiated?
