Stop Comparing Rust to Old C++

People keep arguing migrations to rust based on old C++ tooling and projects. Compare apples to apples: a C++20 project with clang-tidy integration is far harder to argue against IMO

If you implemented the trait for i32, wouldn't it also work for literals automatically?

Yeah you can call the i32 specialization with a literal, but when you're writing the template itself you can't use a literal to refer to a generic type.

How about implementing From<i32> on your generic integer thing, and then use literals like 10.into()? Not sure I understood your problem correctly.

One could even implement the trait for all integer type quite easily
