What's great when you learn D with Coedit is its "runnable module" system.

With a simple click, you can execute a module or run its unit tests, it even works if the module has a GUI. This feature is definitively a time saver.

Here is a small video that shows how it helps me to develop a visual framework. As a project I have a whole static library, but when I want to test a fix, a new feature or whatever I use some runnable modules.

Without any project, any command-line (except the first script line which is used to pass additional linker commands) I can almost directly see the results:

Note that this is also possible thanks to DMD speed, even if the whole logic of the runnable modules is a Coedit thing (for example all the --libman-- entries are always passed, which allow runnable modules to include complex stuffs, like here, a whole visual GUI framework).
