Ah.  Does that mean that import.algorithms is need to use sort()?

I'm assuming here that it's safe to call sort() on the .keys property of 
the dynamic array.  This enables me to go:

foreach (key; aa.keys.sort()) {...}

instead of the much more complex code I'm currently writing which gets 
the keys, sorts them and then uses them in the foreach.  I had actually 
written a generic function to do all of that but now find all the work 
was unnecessary :-).

As I learn more about D I'm finding I can go back and simplify a lot of 
my code.  I'm going to reread Andrei's book to see what I missed the 
first time.

PS I think I need to read more about component programming as I'm 
beginning to suspect I don't understand it fully.
