D equivalent of the X macro?

[H. S. Teoh via Digitalmars-d]

I was reading this article of Walter's:

        http://www.drdobbs.com/cpp/the-x-macro/228700289

Which is a neat trick that I wish I'd known back when I was writing
C/C++. But the thought crossed my mind: what's the D equivalent of the X
macro, since D doesn't have macros? Any ideas?
