Exception Handling

Exception handling in S++ follows Rust’s model, using a result-type for error handling, and a ? postfix operator for error propagation. The std::result::Res[T, E] type is used to represent a result that can either be a value of type T or an error of type E. The Pass[T] and Fail[E] types are used to wrap values inside Res[T, E], where Pass[T] represents a successful result with a value of type T, and Fail[E] represents an error with a value of type E.
