Regardless of what folks decide, I ask that everyone keep one thing in mind (which so far in this thread has not been mentioned): This is an open-source project. What guarantee is there that all members of the project (at the time, or in the future) are going to understand all the intricacies and C++ nomenclature? An example: I used to partake in a project called suPHP (an Apache module + setuid binary wrapper). The author, at one point during a minor release, migrated every single piece over to C++. What happened afterwards wasn't very pretty. Many of the contributing members could no longer contribute, because they did not know C++ (I myself fall into this category). There were a ton of STL-related problems depending upon what compiler you were using, and what version (especially prominent with gcc). Ultimately, the number of contributed patches dropped severely, while the number of bug reports increased. This story is not meant to reflect on C++ the language. I hope readers understand the point of the story, and take into considerations the pros and cons of said choice. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
