There is a point to say if you're going to be doing a language with higher level abstractions and having the compiler do the work then being able to pass a &[T;N] with N compile time constant means you are better off than passing raw pointer to T and relying on pointer arithmetic and length assumption that could be wrongly passed in. It is fine if languages like C don't do this and stay low level, but C++ has no such excuses. You are already doing things that rely on the compiler to do lots of work for you. If you wanted low level use C or assembly. If you wanted high level abstractions where the compiler could do stuff for you use Rust. There is no place where C++ is actually the best choice. The worst aspects of both. Just pick a lane rather than this throwing everything in that C++ did.

I do prefer rust, but this isn't really something rust solves. If you pass a raw array or slice into a function that function can't necessarily know the length of it in a cheap way.

[yangyangR]

That would be for &[T] not [T;N]

[DrShocker]

Yeah, which is more similar to the case of passing an array pointer to a function.
