Given this aims to be a general purpose math library for use in various other libraries applications for axiodl, we can annotate functions that return by value or reference with [[nodiscard]] where it's very obvious that not making use of the return value is a bug. This allows the compiler to diagnose and emit warnings for these API misuses at compile-time, preventing silent bugs from occurring. Any cases where not using the return value is desirable may still be casted to void in order to silence warnings.
