You mean things like this?
void foo()
{
OUString a;
}
Yes, even in practice, see attachment.
But I think this one is generic enough that it should be actually preferably
done upstream. There are already GCC/Clang attributes pure and const for
marking functions, so there could be a similar attribute to mark ctors/dtors
of classes where the ctor/dtor themselves do not have any side-effects (for a
suitable definition of side-effect).
