I sometimes dream of a source code editor that would allow inline diagrams and nicele rendered documentation and or equations. This could apply to any language that has support for multiline comments.
For example, a code like this, (where md stands for markdown)
/*md
Square value of *any* type| #include <atomic> | |
| #include <future> | |
| #include <iostream> | |
| class AsyncRaiiExample | |
| { | |
| public: | |
| AsyncRaiiExample() : mStopRequired(false) | |
| { |
| #include <future> | |
| class MyThreadedCameraCalibComputer | |
| { | |
| public: | |
| struct GuiCalibInfo | |
| { | |
| cv::Mat mImage; | |
| std::string result; | |
| std::string userInstruction; |
