I always dreamed of language without operator overloading, but with builtin vectors and matrices. Maybe they could be easily mapped to SIMD instructions. They can have a bit different operator (like in one PEP [1]).

I know that there are intrinsics for C, but they are non portable. Maybe except NaCl [2].

Also is concatenation of strings only done through usage of $"^(variable)" syntax?
