If that's what you are planning, I can tell you right now it's not enough. 
Much of the things IDEs need is not present in ddoc. Just off hand, I'd say 
more than 50% of the IDE features I use from C#/VS would need (much) more 
than ddoc has. What would be better is a dump of a fully annotated AST from 
just before it's passed off for optimization and code gen.
