We are using py++ for wrapping libraries in an experimental compiler. Roman has always been very helpful if there have been questions or problems with the tools.
Not worth anything if you can't get it to work. The install process is a joke, I've spent hours building random dependencies (most of which are just as problematic with their own dependencies), setting environment flags, diagnosing unhelpful error messages, etc. The documentation is outdated, generally broken, and just an overall mess. While the concept looks amazing, I can only assume it is truly unfinished/buggy/clunky to match the install process. If it ever is finished and properly packaged, then I'll take another look. And I do hope that day comes.
There are no 4 star reviews.
