http://www.digitalmars.com/d/2.0/attribute.html#abstract (and similarly 1.0)
"Classes become abstract if they are defined within an abstract attribute, or
if any of the virtual member functions within it are declared as abstract."

The compiler is behaving correctly, therefore this is an enhancement request.
