[Blobs] Blobs as a visual interface for DSEL

Hi, I have always thought there was a strong connection between a DSEL and a diagram editor. But if Haskell is a language of choice for DSEL, creating a diagramming front-end seemed in Haskell seemed quite a lot of work. And good diagramming tools are very rare: I use Dia, but it would require customizing shapes and other things to be used as a diagram producer, and needs a post-processor to adapt its file-format to the input of a DSEL processor. So I have great hope that Blobs will be the solution, when it is released, towards a full Haskell tool-chain. Alain
