+// Allow projects to #define BOOST_PARAMETER_DISABLE_PERFECT_FORWARDING to
+// turn off perfect forwarding as necessary.  Otherwise, also require correct
+// SFINAE support, needed explicitly by tagged_argument & keyword & cast;
+// correct function template ordering, needed by the code generation macros;
+// rvalue references, needed throughout; variadic templates, needed by
+// parameters; function template default arguments, needed by the code
+// generation macros; and the ability to handle multiple parameter packs,
+// needed by parameters.  Older versions of GCC either don't have the latter
+// ability or cannot disambiguate between keyword's overloaded
+// operators.  Older versions of Clang either fail to compile due to
+// differences in length between parameter packs 'Args' and 'args' or fail at
+// runtime due to segmentation faults.
