Generating the JSON build description should entirely 
deterministic. With Lua, this can be guaranteed. You can create a 
sandbox where only certain operations are permitted. For example, 
reading files is permitted, but writing to them is not. I can 
also intercept all file reads and mark the files that get read as 
dependencies.

It certainly could be done in D, or any other language for that 
matter. All that needs to be done is to write a program that can 
output the fundamental JSON build description.
