After the initial test if the owning_reference is returned no further null_checks are necessary since the reference cannot be set to null.

Hi! Sorry it took so long to touch base on this. I think the current design is sufficient at least for now so I'll close this, but I appreciate the idea. Thanks! |

This patch represents a suggestion:
Default new should return std::optional<owning_reference> with owning_reference managing the life time of the object in a similar way as a unique_ptr would with the exception that it is not allowed to be null.
This will allow to move the reference around without null checks.
