Research direction

Read WG21-P2927R3, WG21-P3748R0, and the applicable portion of WG21-P3981R2 to establish the required exception_ptr_cast behavior and return types. Check the feature-test macro requirement and the note that C++26 feature pull requests are not yet being accepted; completion would require implementing the specified feature and validating its tests once work is open for contribution.
