For whatever it's worth, I enjoy explaining things to others so each time a topic recurs I can do that where it seems appropriate. And hey I can pass on things I didn't know about and then learned here, for example that's why I tell people about WUFFS, can you do all the bounds checking at compile time? Sure, for a price. And that price (generality) might be easily affordable in which case using Rust, never mind C++ is very silly because WUFFS was offering you better performance and total safety if you can do without generality.
