Got it.

Excellent. Because all of the keys are immutable strings and are 
known at compile time, enum seems like it should be well suited 
for the job. I will try this too.

On a side note: I am working my way through your book, Ali. It 
really is very helpful for learning D, and for pointing out 
things that are not always clear from reading the documentation 
alone. I will admit, however, that I am not able to absorb all of 
the more subtle aspects yet. So this is an iterative process 
(read some, write code, re-read and read some more, write code, 
...)

Thank you for your help.
