To be used approprietly, c++ requires much more discipline than c. Doing this
for a community-based project is very hard. Doing this with people who often
are scientist first and programmers second even harder.
This is very important. I am not sure it is doable. Bad C++ is far worse
How about a different variation. How many people writing Python would happily
give up the following:
1) lists
2) dictionaries
3) default types
4) classes
5) automatic dellocation of memory
1) std::vector
2) std::unordered_map
3) auto
4) class
