Attaching additional data to types, that can't be specified otherwhere. 
This should help with metaprogramming-like stuff.

For example serialization. How do you specify that a field shouldn't be 
part of the serialized data? Java has an extra keyword attribute like 
"transient" (comes from before attributes were introduced). C# uses what 
we call annotation in this thread. How would you do this in D?
