As described, the DeclDef grammar allows Invariant and UnitTest at module
scope.  The compiler only permits them within classes, structs, and unions,
which seems more correct to me.  Given that and bug 2651, I think the grammar
should be modified as:

Module:
        DeclDefs

DeclDefs:
        DeclDef
        DeclDef DeclDefs

DeclDef:
        AttributeSpecifier
        ImportDeclaration
        EnumDeclaration
        ClassDeclaration
        InterfaceDeclaration
        AggregateDeclaration
        Declaration
        UnitTest
        StaticConstructor
        StaticDestructor
        DebugSpecification
        VersionSpecification
        MixinDeclaration
        ;

ClassBodyDeclaration:
        AggregateDeclDef
        Constructor
        Destructor
        ClassAllocator
        ClassDeallocator

StructBodyDeclaration:
        AggregateDeclDef
        StructAllocator
        StructDeallocator
        StructConstructor
        StructPostblit
        StructDestructor

AggregateDeclDef:
        DeclDef
        Invariant
        UnitTest

Unit tests are correctly permitted at the module level. A unit test can be used
to test free functions as well as class/struct methods.

Yes, I see that now.  I'm now thinking that to make the distinction in the
grammar you need two different versions of AttributeSpecifier - one for module
scope that references DeclDef and another for class/struct scope where
invariant is allowed.

ClassBodyDeclaration and StructBodyDeclaration still need to reference some
kind of DeclDef, though.
