I'm assuming the callers of this function didn't need updating because they
were already using unique_ptr and unique_ptr's T* ctor? It'd be nice to
update those callers from this:
unique_ptr<T> p(func());
to
unique_ptr<T> p = func();
when func changes return type from T* to unique_ptr<T> to help indicate
that there's no explicit conversion going on anymore (makes the code look
(and be) a bit 'safer' imho).
