### 2060. `unique_ptr<T[]>(nullptr_t)` missing `noexcept`

Discussion:

The synopsis in 20.3.1.3 [unique.ptr.single] specifies:

>     constexpr unique_ptr(nullptr_t) noexcept

which looks correct to me. However the corresponding constructor in 20.3.1.4 [unique.ptr.runtime] is missing `noexcept`:

>     constexpr unique_ptr(nullptr_t) : unique_ptr() { }

[Bloomington, 2011]

Closed as NAD Editorial.

Proposed resolution:

This wording is relative to the FDIS.

1. Modify the synopsis in 20.3.1.4 [unique.ptr.runtime]:

   >     namespace std {
   >       template <class T, class D> class unique_ptr<T[], D> {
   >       public:
   >         typedef see below pointer;
   >         typedef T element_type;
   >         typedef D deleter_type;

   >         // 20.7.1.3.1, constructors
   >         constexpr unique_ptr() noexcept;
   >         […]
   >         constexpr unique_ptr(nullptr_t) noexcept : unique_ptr() { }

   >         […]
   >       };
   >     }
