Discussion:

After applying LWG 2740⁽ⁱ⁾, we have:

constexpr const T* operator->() const;
constexpr T* operator->();

-1- Requires: *this contains a value.

-2- Returns: val. -3- Throws: Nothing. -4- Remarks: These functions shall be constexpr functions.

Paragraph 4 is completely superfluous. We already said these functions were constexpr in the synopsis. Can it be removed?

Priority 2

Jonathan notes: Although Richard is correct, I suggest we don't strike the paragraph, so that we remember to fix it as part of 2833⁽ⁱ⁾, when we know how to say this properly.

Status to Open; also see 7.7 [expr.const]/6 and 2289⁽ⁱ⁾.

The revised wording provided by LWG 2833⁽ⁱ⁾ should resolve this issue as well.
