-// TESTING std::function<...>::__not_null(Callable)
-//
-// Concerns:
-//  1) The call __not_null(Callable) is well formed and correct for each
-//     possible 'Callable' type category. These categories include:
-//      1a) function pointers
-//      1b) member function pointer
-//      1c) member data pointer
-//      1d) callable class type
-//      1e) lambdas
-//    Categories 1a, 1b, and 1c are 'Nullable' types. Only objects of these
-//    types can be null. The other categories are not tested here.
-//  3) '__not_null(Callable)' is well formed when the call signature includes
-//      varargs.
-//  4) '__not_null(Callable)' works for Callable types with all arities less
-//     than or equal to 3 in C++03.
-//  5) '__not_null(Callable)' works when 'Callable' is a member function
-//     pointer to a cv or ref qualified function type.
-//
-// Plan:
-//  1 For categories 1a, 1b and 1c define a set of
-//    'Callable' objects for this category. This set should include examples
-//    of arity 0, 1, 2 and possible 3 including versions with varargs as the
-//    last parameter.
-//
-//  2 For each 'Callable' object in categories 1a, 1b and 1c do the following.
-//
-//    1 Define a type 'std::function<Sig>' as 'F' where 'Sig' is compatible with
-//      the signature of the 'Callable' object.
-//
-//    2 Create an object of type 'F' using a null pointer of type 'Callable'.
-//      Check that 'F.target<Callable>()' is null.
-//
-//    3 Create an object of type 'F' that is not null. Check that
-//      'F.target<Callable>()' is not null and is equal to the original
-//      argument.
