While that's technically right, I'd like to skip further 
explanations of the syntax.  The same as I skipped why the 
problem is solved by such code at all (and it's even less 
obvious).  In both cases, careful explanations would require a 
good paragraph or two, but are beside the point.  The point of 
the article is more to just show how it feels and to spark 
interest than to explain everything.  On the other hand, if I had 
to write a guide for competitive programmers on how to use D, 
such things sure would be included.
