/// \brief Class which can simulate a type-safe variadic function.
///
/// The VariadicFunction class template makes it easy to define
/// type-safe variadic functions where all arguments have the same
/// type.
///
/// Suppose we need a variadic function like this:
///
///   ResultT Foo(const ArgT &A_0, const ArgT &A_1, ..., const ArgT &A_N);
///
/// Instead of many overloads of Foo(), we only need to define a helper
/// function that takes an array of arguments:
///
///   ResultT FooImpl(ArrayRef<const ArgT *> Args) {
///     // 'Args[i]' is a pointer to the i-th argument passed to Foo().
///     ...
///   }
///
/// and then define Foo() like this:
///
///   const VariadicFunction<ResultT, ArgT, FooImpl> Foo;
///
/// VariadicFunction takes care of defining the overloads of Foo().
///
/// Actually, Foo is a function object (i.e. functor) instead of a plain
/// function.  This object is stateless and its constructor/destructor
/// does nothing, so it's safe to create global objects and call Foo(...) at
/// any time.
///
/// Sometimes we need a variadic function to have some fixed leading
/// arguments whose types may be different from that of the optional
/// arguments.  For example:
///
///   bool FullMatch(const StringRef &S, const RE &Regex,
///                  const ArgT &A_0, ..., const ArgT &A_N);
///
/// VariadicFunctionN is for such cases, where N is the number of fixed
/// arguments.  It is like VariadicFunction, except that it takes N more
/// template arguments for the types of the fixed arguments:
///
///   bool FullMatchImpl(const StringRef &S, const RE &Regex,
///                      ArrayRef<const ArgT *> Args) { ... }
///   const VariadicFunction2<bool, const StringRef&,
///                           const RE&, ArgT, FullMatchImpl>
///       FullMatch;
///
/// Currently VariadicFunction and friends support up-to 3
/// fixed leading arguments and up-to 32 optional arguments.
