[section:function Decomposing Function Types]

The class template __function_traits extracts information from function types
(see also __is_function).  This traits class allows you to tell how many arguments
a function takes, what those argument types are, and what the return type is.

[*Synopsis]

   template <std::size_t Align>
   struct __function_traits;
