### Regular SOPs

When `Sign` is one of `"+"`, `"-"`, `"*"`, `"/"`, `"%"`, `"++"`, `"--"`, `"=="`, `"!="`, `">"`, `"<"`, `">="`, `"<="`, `"<=>"`, `"&&"`, `"||"`, `"&"`, `"|"`, `"^"`, `"<<"`, `">>"`, `","`, `"->*"`, `"()"`, `"[]"`,
When `Sign` is one of `"+"`, `"-"`, `"*"`, `"/"`, `"%"`, `"=="`, `"!="`, `">"`, `"<"`, `">="`, `"<="`, `"<=>"`, `"&&"`, `"||"`, `"&"`, `"|"`, `"^"`, `"<<"`, `">>"`, `","`, `"->*"`, `"()"`, `"[]"`,

```cpp
// (3)
template <class P, class D, class R, class... Args>
struct accessor<P, D, R(Args...) cv ref noex> {
R operator sop (Args... args) cv ref noex;
}
};
```

`(3)` Provides an `operator sop(Args...)` with the same *cv ref noex* specifiers as of the overload type. `accessor::operator sop(Args...)` is equivalent to `return invoke<D, R(Args...) cv ref noex>(static_cast<P cv <ref ? ref : &>>(*this), std::forward<Args>(args)...)`.

### `!` and `~`
### `"!"` and `"~"`

When `Sign` is either `!` and `~`,
When `Sign` is either `"!"` or `"~"`,

```cpp
// (4)
template <class P, class D, class R>
struct accessor<P, D, R() cv ref noex> {
R operator sop () cv ref noex;
}
};
```

`(4)` Provides an `operator sop()` with the same *cv ref noex* specifiers as of the overload type. `accessor::operator sop()` is equivalent to `return invoke<D, R() cv ref noex>(static_cast<P cv <ref ? ref : &>>(*this))`.

### `"++"` and `"--"`

When `Sign` is either `"++"` or `"--"`,

```cpp
// (5)
template <class P, class D, class R>
struct accessor<P, D, R() cv ref noex> {
/* see below */ operator sop () cv ref noex;
};

// (6)
template <class P, class D, class R>
struct accessor<P, D, R(int) cv ref noex> {
R operator sop (int) cv ref noex;
};
```

`(5)` Provides a prefix `operator sop()` with the same *cv ref noex* specifiers as of the overload type. `accessor::operator sop()` calls `invoke<D, R() cv ref noex>(static_cast<P cv <ref ? ref : &>>(*this))` and returns `static_cast<P cv <ref ? ref : &>>(*this)`.

`(6)` Provides a postfix `operator sop(int)` with the same *cv ref noex* specifiers as of the overload type. `accessor::operator sop(int)` is equivalent to `return invoke<D, R(int) cv ref noex>(static_cast<P cv <ref ? ref : &>>(*this), 0)`.

### Assignment SOPs

When `Sign` is one of `"+="`, `"-="`, `"*="`, `"/="`, `"%="`, `"&="`, `"|="`, `"^="`, `"<<="`, `">>="`,

```cpp
// (5)
// (7)
template <class P, class D, class R, class Arg>
struct accessor<P, D, R(Arg) cv ref noex> {
/* see below */ operator sop (Arg arg) cv ref noex;
}
};
```

`(4)` Provides an `operator sop(Arg)` with the same *cv ref noex* specifiers as of the overload type. `accessor::operator sop(Arg)` calls `invoke<D, R(Arg) cv ref noex>(static_cast<P cv <ref ? ref : &>>(*this), std::forward<Arg>(arg))` and returns `static_cast<P cv <ref ? ref : &>>(*this)`.
`(7)` Provides an `operator sop(Arg)` with the same *cv ref noex* specifiers as of the overload type. `accessor::operator sop(Arg)` calls `invoke<D, R(Arg) cv ref noex>(static_cast<P cv <ref ? ref : &>>(*this), std::forward<Arg>(arg))` and returns `static_cast<P cv <ref ? ref : &>>(*this)`.

## Right-Hand-Side Operand Specializations

```cpp
// (6)
// (8)
template <class P, class D, class... Os>
requires(sizeof...(Os) > 1u && (std::is_constructible_v<accessor<P, D, Os>> && ...))
struct accessor<P, D, Os...> : accessor<P, D, Os>... {};
```

`(6)` When `sizeof...(Os)` is greater than `1`, and `accessor<P, D, Os>...` are default-constructible types, inherits all `accessor<P, D, Os>...` types.
`(8)` When `sizeof...(Os)` is greater than `1`, and `accessor<P, D, Os>...` are default-constructible types, inherits all `accessor<P, D, Os>...` types.

When `Rhs` is `true`, the other specializations are defined as follows, where `sizeof...(Os)` is `1` and the only type `O` qualified with `cv ref noex`:

`(7)` Provides a `friend operator sop(Arg arg, P cv <ref ? ref : &> self)` with the same *noex* specifiers as of the overload type. `accessor::operator sop(Arg arg, P cv <ref ? ref : &> self)` is equivalent to `return invoke<D, R(Arg) cv ref noex>(static_cast<P cv <ref ? ref : &>>(self), std::forward<Arg>(arg))`.
