Most of the constructors are supposed to be only a call of new TheInstance(arguments) or an equivalent; so let's just change the constructor caller accordingly, to accept unacquired new instance. If there are exceptions that need to do more heavy lifting, they do not have to use the constructor feature, or there can be a wrapper for the real implementation, doing the additional work in their (C++) constructor.
