Objections were raised, the paper is sent back to an in-person meeting.

It was suggested to have exception_ptr_cast return a new type that would own the exception, which would solve more generally the dangling issue P3416 is trying to avoid.

However, no such paper has materialized, which leaves us 2 options

• approve P3416R0
• hope someone makes a nb comment
