The only downturn I see is that the default tns is not fallen back on 
when __namespace__ is not defined. So this is likely to be wrong in the 
general case. I don't know how to reconcile this though, since 
__namespace__ will always return something and I would think comparing 
this to the class's module name would be rather hackish.
