Proposed resolution (approved by CWG 2022-11-09):

Change in 13.10.3.4 [temp.deduct.conv] paragraph 1 as follows:

... If the conversion-function-id is constructed during overload resolution ([over.match.funcs]), the following transformations rules in the remainder of this subclause apply.

Change in 13.10.3.4 [temp.deduct.conv] bullet 5.2 as follows:

However, certain attributes of A may be ignored:

• ...
• If the original A is a function pointer or pointer-to-member-function type with a potentially-throwing exception specification (14.5 [except.spec]), its noexcept the exception specification.
• ...

[Accepted as a DR at the November, 2022 meeting.]

The rule in 13.10.3.4 [temp.deduct.conv] bullet 5.2 seems to allow

template<class T,bool B>
using get=T(*)() noexcept(B);

struct A {
 template<class T>
 operator get<T,false>() const;
};

auto *p=A().operator get<int,true>();
