Is there any use for unique_ptr with array?

std::unique_ptr has support for arrays, for instance:

std::unique_ptr p(new int[10]);

but is it needed? probably it is more convenient to use std::vector or std::array.

Do you find any use for that construct?

Some people do not have the luxury of using std::vector, even with allocators. Some people need a dynamically sized array, so std::array is out. And some people get their arrays from other code that is known to return an array; and that code isn't going to be rewritten to return a vector or something.

By allowing unique_ptr, you service those needs.

In short, you use unique_ptr when you need to. When the alternatives simply aren't going to work for you. It's a tool of last resort.
