[Mono-devel-list] System.Web/System.Web.UI - patch (code synchronization between Mono and Mainsoft)

[Rafael Teixeira]

I maybe due to the fact that Java, doesn't have value objects other
than the basic crowd (int, long, double, float...), and to be able to
have the value semantics GH has to create lots of
imuttable/cloneable/value-comparable objects...

Just guessing...
