+Exception handling
+==================
+
+PSTL backends are expected to report errors (i.e. failure to allocate) by returning a disengaged `optional` from their
+implementation. Exceptions shouldn't be used to report an internal failure-to-allocate, since all exceptions are turned
+into a program termination at the front-end level. When a backend returns a disengaged `optional` to the frontend, the
+frontend will turn that into a call to `std::__throw_bad_alloc();` to report the internal failure to the user.
