I've asked this same question before and my answer is mostly the 
same as dicebot: I think reflection is the important bit. Of 
course, even there it is sometimes useful to break it into two 
steps (one just prints the data out kinda like dmd -X then a 
regular program reads it and generates the code), but I find it 
really useful to read D code and generate stuff based on that.

it is actually pretty trivial in make too...
