///
/// <tt>callable_context\<\></tt> is a base class that implements
/// the context protocol by passing fanned-out expression nodes to
/// the derived context, making it easy to customize the handling
/// of expression types by writing function overloads. Only those
/// expression types needing special handling require explicit
/// handling. All others are dispatched to a user-specified
/// default context, \c DefaultCtx.
///
/// <tt>callable_context\<\></tt> is defined simply as:
///
/// \code
/// template<typename Context, typename DefaultCtx = default_context>
/// struct callable_context
/// {
/// template<typename Expr, typename ThisContext = Context>
/// struct eval
/// : mpl::if_<
/// is_expr_handled_<Expr, Context> // For exposition
/// , callable_eval<Expr, ThisContext>
/// , typename DefaultCtx::template eval<Expr, Context>
/// >::type
/// {};
/// };
/// \endcode
///
/// The Boolean metafunction <tt>is_expr_handled_\<\></tt> uses
/// metaprogramming tricks to determine whether \c Context has
/// an overloaded function call operator that accepts the
/// fanned-out constituents of an expression of type \c Expr.
/// If so, the handling of the expression is dispatched to
/// <tt>callable_eval\<\></tt>. If not, it is dispatched to
/// the user-specified \c DefaultCtx.
///
/// Below is an example of how to use <tt>callable_context\<\></tt>:
///
/// \code
/// // An evaluation context that increments all
/// // integer terminals in-place.
/// struct increment_ints
/// : callable_context<
/// increment_ints const // derived context
/// , null_context const // fall-back context
/// >
/// {
/// typedef void result_type;
///
/// // Handle int terminals here:
/// void operator()(proto::tag::terminal, int &i) const
/// {
/// ++i;
/// }
/// };
/// \endcode
///
/// With \c increment_ints, we can do the following:
///
/// \code
/// literal<int> i = 0, j = 10;
/// proto::eval( i - j * 3.14, increment_ints() );
///
/// assert( i.get() == 1 && j.get() == 11 );
