@ tastyminerals  Thanks for your help on this. These comments, 
combined with the others, are making my climb of the D learning 
curve much quicker.

I'm not a gitHub fan, but I like the mir functions; and it looks 
like I have to download mir before using it.
mir has quite a few .d files..Is there a quick way to download it 
?
