Which D features to emphasize for academic review article

[TJB]

Hello D Users,

The Software Editor for the Journal of Applied Econometrics has 
agreed to let me write a review of the D programming language for 
econometricians (econometrics is where economic theory and 
statistical analysis meet).  I will have only about 6 pages.  I 
have an idea of what I am going to write about, but I thought I 
would ask here what features are most relevant (in your minds) to 
numerical programmers writing codes for statistical inference.

I look forward to your suggestions.

Thanks,

TJB
