/!\ Shameless autopromotion incoming /!\I have recently put some effort into exploring alternatives to visitor pattern and see what can be done in D. I ended up with a solution which is a real improvement compared to plein old visitor pattern and wanted to share this here.
I think this is short enough to be a good example to show what can be done with D capabilities.
