Good luck making all your teammates use these boost templates and use them correctly. And debugging these layers of templates. A classic from the old Rust FAQ: >> I already write perfect C++. What does Rust give me? > Modern C++ includes many features that make writing safe and correct code less error-prone, but it’s not perfect, and it’s still easy to introduce unsafety. This is something the C++ core developers are working to overcome, but C++ is limited by a long history that predates a lot of the ideas they are now trying to implement. > Rust was designed from day one to be a safe systems programming language, which means it’s not limited by historic design decisions that make getting safety right in C++ so complicated. In C++, safety is achieved by careful personal discipline, and is very easy to get wrong. In Rust, safety is the default. It gives you the ability to work in a team that includes people less perfect than you are, without having to spend your time double-checking their code for safety bugs.
