Similar efforts are useful almost as the Haskell GHC compiler 
extensions: to allow the community to try to use features not yet 
present in the language, to judge them better, allowing to 
understand if they are worth putting in the language, and trying 
few alternative implementation ideas looking for the best one of 
them.

But to do this well, people need to understand such extensions 
very well. So instead of just offering the source code and one 
uncommented example, I suggest to explain each feature, why they 
are present, what design choices you have taken and why, and how 
to use them in some common cases, with few specific examples.

This will make your work useful for the development of the 
mainstream D too.
