OK, thanks I can see the merit in that. But on the other hand is it 
really a good idea to put the same 'use' statement so many times in what 
could amount to 20 or more controllers? Is there a start-up penalty if I 
have to load multiple modules in each controller separately instead of 
once each in MyApp.pm?
