I understand you being angry about this. It would be hard not to be. It would 
have been a lot better if Andrei and I had noticed this before much was invested 
in it.

This looks like it's creeping towards inventing a new script programming 
language. Adding loops, switch statements, functions, etc., can't be far off. 
Before you get too far down this path, consider:

1. JSON has a superset programming language - Javascript - which has 
conventional syntax rather than the DEP4 proposal for odd syntax like

     if dub-version="<0.9.24"

which I would strongly recommend against. And, we already have a Javascript 
engine written in D:


2. D itself can be used as a scripting language (when # is the first character 
in the source code). Having DUB use this might be quite interesting.

 From my other post in this thread about all the problems with going with SDL:

"With a standard json parser in Phobos, zip zap boom you're done. You don't have 
to design it, argue about it, build it, document it, debug it, test it, optimize 
it, explain it, deal with bug requests, deal with enhancement requests, deal 
with legacy compatibility, build a converter, build a gui tool for it, etc."
