// Facilities for dealing with types which always manage Python
// objects. Some examples are object, list, str, et. al. Different
// to_python/from_python conversion rules apply here because in
// contrast to other types which are typically embedded inside a
// Python object, these are wrapped around a Python object. For most
// object managers T, a C++ non-const T reference argument does not
// imply the existence of a T lvalue embedded in the corresponding
// Python argument, since mutating member functions on T actually only
// modify the held Python object.
//
// handle<T> is an object manager, though strictly speaking it should
// not be. In other words, even though mutating member functions of
// hanlde<T> actually modify the handle<T> and not the T object,
// handle<T>& arguments of wrapped functions will bind to "rvalues"
// wrapping the actual Python argument, just as with other object
// manager classes. Making an exception for handle<T> is simply not
// worth the trouble.
//
// borrowed<T> cv* is an object manager so that we can use the general
// to_python mechanisms to convert raw Python object pointers to
// python, without the usual semantic problems of using raw pointers.

//
// T is an Object Manager
// p is a PyObject*
// x is a T

// * object_manager_traits<T>::is_specialized == true
//
// * T(detail::borrowed_reference(p))
// Manages p without checking its type
//
// * get_managed_object(x, boost::python::tag)
// Convertible to PyObject*
//
// Additional requirements if T can be converted from_python:
//
// * T(object_manager_traits<T>::adopt(p))
// steals a reference to p, or throws a TypeError exception if
// p doesn't have an appropriate type. May assume p is non-null
//
// * X::check(p)

// Data management for potential rvalue conversions from Python to C++
// types. When a client requests a conversion to T* or T&, we
// generally require that an object of type T exists in the source
// Python object, and the code here does not apply**. This implements
// conversions which may create new temporaries of type T. The classic
// example is a conversion which converts a Python tuple to a
// std::vector. Since no std::vector lvalue exists in the Python
// object -- it must be created "on-the-fly" by the converter, and
// which must manage the lifetime of the created object.
//
// Note that the client is not precluded from using a registered
// lvalue conversion to T in this case. In other words, we will
// happily accept a Python object which /does/ contain a std::vector
// lvalue, provided an appropriate converter is registered. So, while
// this is an rvalue conversion from the client's point-of-view, the
// converter registry may serve up lvalue or rvalue conversions for
// the target type.
//
// ** C++ argument from_python conversions to T const& are an
// exception to the rule for references: since in C++, const
// references can bind to temporary rvalues, we allow rvalue
// converters to be chosen when the target type is T const& for some
// T.

// Conversions begin by filling in and returning a copy of this
// structure. The process looks up a converter in the rvalue converter
// registry for the target type. It calls the convertible() function
// of each registered converter, passing the source PyObject* as an
// argument, until a non-null result is returned. This result goes in
// the convertible field, and the converter's construct() function is
// stored in the construct field.
//
// If no appropriate converter is found, conversion fails and the
// convertible field is null. When used in argument conversion for
// wrapped C++ functions, it causes overload resolution to reject the
// current function but not to fail completely. If an exception is
// thrown, overload resolution stops and the exception propagates back
// through the caller.
//
// If an lvalue converter is matched, its convertible() function is
// expected to return a pointer to the stored T object; its
// construct() function will be NULL. The convertible() function of
// rvalue converters may return any non-singular pointer; the actual
