In a bunch of cases, this actually ends up simplifying the code as to_number will handle something such as: ``` Optional<I> opt; if constexpr (IsSigned<I>) opt = view.to_int<I>(); else opt = view.to_uint<I>(); ``` For us. The main goal here however is to have a single generic number conversion API between all of the String classes.
