Seems this:

I'm guessing that your code is not doing the same thing as the D 
code if you have to use tricks like that just to get it to run. 
Having used Common Lisp, I know your program requires extensive 
knowledge of the language, and was the result of a careful 
optimization exercise - unlike the D code. It's definitely not 
the kind of code you'd write after reading Practical Common Lisp.
