I agree that it's a style issue, but in this case it is actually intentional.  
The longish term plan is to get rid of as many global scope things as 
possible, and rename the remaining ones that cannot be eliminated, if any.  
When this plan starts to become reality, these issues get sorted 
out "properly" - I don't think it'd be good to make cosmetic changes that 
we'd probably want to revert later meanwhile, such as this one.
