// Sometimes you want to give an action explicit template parameters
// that cannot be inferred from its value parameters.  ACTION() and
// ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that
// and can be viewed as an extension to ACTION() and ACTION_P*().
//
// The syntax:
//
//   ACTION_TEMPLATE(ActionName,
//                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
//                   AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
//
// defines an action template that takes m explicit template
// parameters and n value parameters.  name_i is the name of the i-th
// template parameter, and kind_i specifies whether it's a typename,
// an integral constant, or a template.  p_i is the name of the i-th
// value parameter.
//
// Example:
//
//   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
//   // function to type T and copies it to *output.
//   ACTION_TEMPLATE(DuplicateArg,
//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
//                   AND_1_VALUE_PARAMS(output)) {
//     *output = T(::std::get<k>(args));
//   }
//   ...
//     int n;
//     EXPECT_CALL(mock, Foo(_, _))
//         .WillOnce(DuplicateArg<1, unsigned char>(&n));
//
// To create an instance of an action template, write:
//
//   ActionName<t1, ..., t_m>(v1, ..., v_n)
//
// where the ts are the template arguments and the vs are the value
// arguments.  The value argument types are inferred by the compiler.
// If you want to explicitly specify the value argument types, you can
// provide additional template arguments:
//
//   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
//
// where u_i is the desired type of v_i.
//
// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
// number of value parameters, but not on the number of template
// parameters.  Without the restriction, the meaning of the following
// is unclear:
//
//   OverloadedAction<int, bool>(x);
//
// Are we using a single-template-parameter action where 'bool' refers
// to the type of x, or are we using a two-template-parameter action
// where the compiler is asked to infer the type of x?
//
// Implementation notes:
//
// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
// implementing ACTION_TEMPLATE.  The main trick we use is to create
// new macro invocations when expanding a macro.  For example, we have
//
//   #define ACTION_TEMPLATE(name, template_params, value_params)
//       ... GMOCK_INTERNAL_DECL_##template_params ...
//
// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
// to expand to
//
//       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
//
// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
// preprocessor will continue to expand it to
//
//       ... typename T ...
//
// This technique conforms to the C++ standard and is portable.  It
// allows us to implement action templates using O(N) code, where N is
// the maximum number of template/value parameters supported.  Without
// using it, we'd have to devote O(N^2) amount of code to implement all
// combinations of m and n.

// Declares the template parameters.

// function, with arguments a1, a2, ..., a_k.
//
// Notes:
//
//   1. The arguments are passed by value by default.  If you need to
//   pass an argument by reference, wrap it inside std::ref().  For
//   example,
//
//     InvokeArgument<1>(5, string("Hello"), std::ref(foo))
//
//   passes 5 and string("Hello") by value, and passes foo by
//   reference.
//
//   2. If the callable takes an argument by reference but std::ref() is
//   not used, it will receive the reference to a copy of the value,
//   instead of the original value.  For example, when the 0-th
//   argument of the mock function takes a const string&, the action
//
//     InvokeArgument<0>(string("Hello"))
//
//   makes a copy of the temporary string("Hello") object and passes a
//   reference of the copy, instead of the original temporary object,
//   to the callable.  This makes it easy for a user to define an
//   InvokeArgument action from temporary values and have it performed
//   later.
