> There are three major disadvantages of exposing exceptions in the public API:
> * Exposing exceptions in public APIs forces the downstream users to be compiled with {{-fexceptions}}, which might be infeasible in many use cases.
> * It forces other bindings to properly handle all C++ exceptions, which might be infeasible especially when the binding is generated by tools like SWIG.
> * It forces the downstream users to properly handle all C++ exceptions, which can be cumbersome as in certain cases it will lead to undefined behavior (e.g., throwing an exception in a destructor is undefined.)
