Edward Bakker has been blogging his experience of using DSL Tools: http://www.edwardbakker.nl/
This is great feedback for us. Edward, rest assured that we are fixing the "keeping dd in synch with dmd" problem for the V1 release, as one of the many things that we'll be doing.
Indeed, the reason I've been a little quiet on my blog recently is because we have been engaged in an intense period of planning, nailing down the scenarios and feature set that we'll be targeting for V1. I hope to be able to post a roadmap to V1, with some details of those features and scenarios fairly soon after I get back from vacation - should be early September.
