-// * class.cs: Following the comment from 2002-09-26 to AddMethod, I
-// have fixed a remaining problem: not every AddXXXX was adding a
-// fully qualified name.
-//
-// Now everyone registers a fully qualified name in the DeclSpace as
-// being defined instead of the partial name.
-//
-// Downsides: we are slower than we need to be due to the excess
-// copies and the names being registered this way.
-//
-// The reason for this is that we currently depend (on the corlib
-// bootstrap for instance) that types are fully qualified, because
-// we dump all the types in the namespace, and we should really have
-// types inserted into the proper namespace, so we can only store the
-// basenames in the defined_names array.
