I WILL be attending, and I also agree that we should be making use of std::expected, so I will defend that point. I think this is in fact a BSI position, but I would need to check with the chair (CCed). If not, we should raise this at the BSI meeting on Monday.
Cheers,

Hi all,
Sorry but I can't make the session tomorrow.
However, I am keen to keep advocating for error-handling via a std::expected (with an appropriate unexpected value type which captures the various possibilities). I think this is the most ergonomic and least surprising approach.
Even if it is decided not to go down this route, I think the paper would greatly benefit from a proper discussion of the various options. All I can find (sorry if I've missed something) is this bullet point in the R5 revision list:
* stats_error, an exception, is removed, since (C++) math funtions do not throw exceptions

Hi all,
Sorry but I can't make the session tomorrow.
However, I am keen to keep advocating for error-handling via a std::expected (with an appropriate unexpected value type which captures the various possibilities). I think this is the most ergonomic and least surprising approach.
Even if it is decided not to go down this route, I think the paper would greatly benefit from a proper discussion of the various options. All I can find (sorry if I've missed something) is this bullet point in the R5 revision list:
