It's obviously relevant. If it was correct, it would work, and you 
wouldn't be asking here !-)

You're using the class as a bare namespace. FWIW, you could as well use 
the module itself - same effect, simplest code.

I assume the first "import" is a typo. But this sure means you didn't 
run that code.

For which definition of "correct value" ? You didn't import nor execute 
initialize() so far, so at this stage RDE is bound to the bool type 
object. FWIW, note that calling initialize *after* the assignement to 
RDE won't change the fact that RDE will be still bound to the the bool 
type object.

You may want to have a look at how other Python application manage 
application-wide settings.
