Issue ID: 13895
Summary: Declaration grammar is insufficient
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Keywords: spec
Severity: normal
Priority: P1
Component: DMD
Assignee: nob...@puremagic.com

Consider the following code (which is accepted by DMD):
---
void main()
{
abstract class C {}
}
---
This produces the parse tree:
...
NonEmptyStatementNoCaseNoDefault
DeclarationStatement
Declaration
???
AggregateDeclaration
ClassDeclaration
....
The problem is that there is no grammar rule stating that "abstract" is valid
at that location, though it obviously is and should be.
Adding "StorageClasses(opt)" to AggregateDeclaration, or to ClassDeclaration,
InterfaceDeclaration, StructDeclaration, and UnionDeclaration should fix this.
