2 question: internationalization and serialization

[Lloyd Dupont]

Hi I'm a newbie with big ambitions! (Sorry, got spoiled by C#)

Anyhow I'm toying with a D learning project and there are 2 .NET feature 
that will be welcome in this D project:

1. internationalization.
the app will contains a bunch of simple UIs and I was wondering how I would 
go on internationalizing the application. I.e. embed multiple "resource" for 
different languages in the EXE and show the appropriate ones for the target 
/ running computer


2. I'd like a part of my library (in progress) to read / write some 
arbitrary settings. I was thing to use something akin to the 
DataContractSerialization we have in .NET
where I could define a few classes with attribute

[DataContract]
class Root
{
  [DataMember]
  public int Prop1 { get; set; }
  [DataMember]
  public B PropB { get; set; }
}

[DataContract]
class B
{
  [DataMember]
  public string Name { get; set; }
}

a reader / writer class can turn this class (using the atributes) into text 
(XML, JSON, I don't care) and back from text into object instance
How would I implement something similar in D? Is there already a library 
doing it?
