Hi Brian,

thanks for sharing this but it looks to me like a micro-optimisation that  
isn't really worth going against best practice for - by using explicit  
name-mangling.

-        return self.__tagged_values.get(tag, default)
+        return getattr(self, '_Element__tagged_values', {}).get(tag,  
default)

Any improvements higher up the stack (using slots, different Python  
version or compilers like LLVM) are likely to have a more significant  
effect. Might be worth timing a slots-based implementation.
