visual debuggers and a node-based programmatic tools. the former should be able to convert code to graphs and the latter should produce code from graphs. see Luna programming language, or other nodes based systems especially in 3D/VFX like blender, houdini, nuke, etc. for visual debugging I'd like to get graph explorers and instrumentation tools for asynchronous logging (but on debug level, rather than logging embedded in code) and visual cues for dataflow and events, etc. I'd love to spare a little bit of time I have to experiment with such ideas if anyone is down.
