DDL should become official part of DMD

I don't know how complicated that would be (licensing issues, ...), but
as a developer / user I would really like it: It's needed to implement
stuff like addins in a convenient way. And it would be great if we could
finally use statically loaded shared libraries instead of static
compilation of everything (I guess that needs compiler integration, so
it's a good reason to include DDL with dmd ;-)). Also, if you look at
http://www.digitalmars.com/d/1.0/dll.html#Dcode the current way to do D
DLLs for use with D code is not very developer friendly. Exporting flat
functions like getMyClass just doesn't feel right. Now compare that with
DDLs features: http://www.dsource.org/projects/ddl/wiki/AboutDDL .DDL
clearly wins. By the way, I guess most of you know that already, but
http://h3.team0xf.com/devlog/?p=12 has an updated version of DDL with a
new linker.
