@Naios

Being able to construct an object rather than having to copy/move one in would be very useful, particularly for objects that may be expensive to construct, or (for unique_function) immovable objects. (After all, if they're on the heap we can still move the pointer.)

This sounds like a promising feature. Probably I will implement it in the future.
