By the way Johannes, the issue is clear I think. You can't make

Whenever you make a copy of a non-POD value, you have to (for example)
build an exception handling frame to destruct it if, in the meantime, an
exception is thrown. This is not only expensive, but it doesn't work if
the value lives in registers.
What a coincidence. I hit today issue

temporaries of POD structures are impossible?
No. I'm asserting that non-POD values:
1. cannot be put in registers
2. are expensive to make temporaries of, because all the exception safety stuff
has to be added
