[section Common requirements]

All /unspecified-N/ types mentioned in the Synopsis are /CopyConstructible/
and /Assignable/. Their copy constructors and assignment operators do not
throw exceptions. /unspecified-N/`::result_type` is defined as the return type
of the member function pointer passed as an argument to `mem_fn` (`R` in the
Synopsis.) /unspecified-2-1/`::result_type` is defined as `R`.

[section `mem_fn`]

[#mem_fn_1]

    template<class R, class T> ``/unspecified-1/`` mem_fn(R (T::*pmf) ())

* /Returns:/ a function object \u03DD such that the expression \u03DD`(t)` is
equivalent to `(t.*pmf)()` when `t` is an l-value of type `T` or derived,
`(get_pointer(t)->*pmf)()` otherwise.

* /Throws:/ Nothing.

[#mem_fn_2]

    template<class R, class T> ``/unspecified-2/`` mem_fn(R (T::*pmf) () const)

* /Returns:/ a function object \u03DD such that the expression \u03DD`(t)` is
equivalent to `(t.*pmf)()` when `t` is of type `T` /[/`const`/]/ or derived,
`(get_pointer(t)->*pmf)()` otherwise.

* /Throws:/ Nothing.

[#mem_fn_2_1]

    template<class R, class T> ``/unspecified-2-1/`` mem_fn(R T::*pm)

* /Returns:/ a function object \u03DD such that the expression \u03DD`(t)` is
equivalent to `t.*pm` when `t` is of type `T` /[/`const`/]/ or derived,
`get_pointer(t)->*pm` otherwise.

* /Throws:/ Nothing.

[#mem_fn_3]

    template<class R, class T, class A1> ``/unspecified-3/`` mem_fn(R (T::*pmf) (A1))

* /Returns:/ a function object \u03DD such that the expression \u03DD`(t, a1)`
is equivalent to `(t.*pmf)(a1)` when `t` is an l-value of type `T` or derived,
`(get_pointer(t)->*pmf)(a1)` otherwise.

* /Throws:/ Nothing.

[#mem_fn_4]

    template<class R, class T, class A1> ``/unspecified-4/`` mem_fn(R (T::*pmf) (A1) const)

[#mem_fn_5]

    template<class R, class T, class A1, class A2> ``/unspecified-5/`` mem_fn(R (T::*pmf) (A1, A2))

* /Returns:/ a function object \u03DD such that the expression \u03DD`(t, a1, a2)`
is equivalent to `(t.*pmf)(a1, a2)` when `t` is an l-value of type `T` or derived,
`(get_pointer(t)->*pmf)(a1, a2)` otherwise.

* /Throws:/ Nothing.

is equivalent to `(t.*pmf)(a1, a2)` when `t` is of type `T` /[/`const`/]/ or derived,
`(get_pointer(t)->*pmf)(a1, a2)` otherwise.

* /Throws:/ Nothing.
