An approach that might work with existing languages is: To use a traditional flat editor (not a structured editor), but show inferred information around the code. I am thinking of visuals that are akin to http://explainshell.com/ http://explainshell.com/ but a lot more compact. The inferred information need not be shown always; it could be shown dynamically based on the user's context (current line, current function, etc)
