I am by no means an expert at reading standardese - and it might be that I'm
not alone, (library writers might have made the same assumption) but it seems

Doe not make any specification about what get_­return_­object() returns, only
that it is possible to use it either (a) to initialise the return value
directly or (b) to construct a return value object from it.
