We should perhaps become a little more flexible ourselves, but we've finally got a good process going internally, including this as a check. I don't dare disturb the machine now that it is working :-).

Yeah, it all gets a little funky after a while.

It was useful for a while, but it is time to be pulling it out.

Yes, and I think removing much of the __func__ or using __builtin_return_address(0) will help.

Yep.
