It would be great if D could have categories/open classes and you

auto a = new A;

And it should of course work on classes you don't have access to the
source code.
Setting aside the technical issues for the moment, isn't that exactly
what inheritance is supposed to be good for?
A few times I've had the need for this, I've always been able to solve
the problem but it would have been easier with support for this. But to
be honest I don't remember these problems right now, so perhaps it's not
that important.
