<p>
The class template <a class="link" href="../reference/function_traits.html" title="function_traits">function_traits</a>
extracts information from function types (see also <a class="link" href="../reference/is_function.html" title="is_function">is_function</a>).
This traits class allows you to tell how many arguments a function takes,
what those argument types are, and what the return type is.
