Remarks
An instance of the type modifier holds a modified-type that is defined in the following stages:
The type U is defined as remove_reference<Ty>::type.
If is_array<U>::value is true, the modified-type type is remove_extent<U>::type *.
Otherwise, if is_function<U>::value is true, the modified-type type is add_pointer<U>::type.
Otherwise, the modified-type type is remove_cv<U>::type.
