Is it safe to say that these 40 lines of D do the same as your 
324 lines of C++ [1]? This, and your comments on the difficulties 
of building renrem [2] versus doing "rdmd", and the steepness of 
the learning curve (1 year C++ vs 2 weeks D), and the 
productivity (2 hours D vs ?? C++) I think are plenty material 
for a nice little blog.

Mike Parker runs the D blog, and I think he might be interested. 
No need to worry about the english language, you are safe with 
Mike. I'll see if I can get you his attention.
