I've set up a comparison with some notes here:

Very nice comparison style.
What would be an appropriate way to discuss grammar changes?
I think many things should be simplified/clarified.
I'd welcome this. I see a few options, but none is currently perfect:
- in a wiki. both dsource and wiki4d don't seem to have discussion
pages, though. I'm not sure the comparison tables can be converted to
something maintainable - it's currently very verbose html.
- here on the newsgroup. this would probably have the widest audience,
but also might easily get lost. maybe with keeping track of
ideas/results in wiki4d.
- in bugzilla. this might get spread into multiple entries causing loss
of the overview of the overall grammar.
For example, isn't AutoDeclaration already covered by Decl -> StorageClasses
Decl and so on?
Also there are 3 different instances of mixin: MixinExpression, MixinStatement
and MixinDeclaration. Even though they all come down to the same thing.
Modifiers like shared are repeated, e.g. in BasicType, Attribute, TypeSpecialization. Also your proposed TypeWithModifier somewhat replicates parts of BasicType (just without the parentheses)
I think, the different mixin variants are ok, because you might want to
generate different AST for these. But the confusion of
const/shared/immutable etc in Attribute,StorageClass,Types,etc causes a
lot of headaches.
