/**
* @brief A simple smart pointer providing strict ownership semantics.
*
* The Standard says:
*
* An @c auto_ptr owns the object it holds a pointer to. Copying
* an @c auto_ptr copies the pointer and transfers ownership to the
* destination. If more than one @c auto_ptr owns the same object
* at the same time the behavior of the program is undefined.
*
* The uses of @c auto_ptr include providing temporary
* exception-safety for dynamically allocated memory, passing
* ownership of dynamically allocated memory to a function, and
* returning dynamically allocated memory from a function. @c
* auto_ptr does not meet the CopyConstructible and Assignable
* requirements for Standard Library container elements and thus
* instantiating a Standard Library container with an @c auto_ptr
* results in undefined behavior.
*
* Quoted from [20.4.5]/3.
*
* Good examples of what can and cannot be done with auto_ptr can
* be found in the libstdc++ testsuite.

/** @defgroup binders Binder Classes
* @ingroup functors
*
* Binders turn functions/functors with two arguments into functors
* with a single argument, storing an argument to be applied later.
* For example, a variable @c B of type @c binder1st is constructed
* from a functor @c f and an argument @c x. Later, B's @c
* operator() is called with a single argument @c y. The return
* value is the value of @c f(x,y). @c B can be @a called with
* various arguments (y1, y2, ...) and will in turn call @c
* f(x,y1), @c f(x,y2), ...
*
* The function @c bind1st is provided to save some typing. It takes the
* function and an argument as parameters, and returns an instance of
* @c binder1st.
*
* The type @c binder2nd and its creator function @c bind2nd do the same
* thing, but the stored argument is passed as the second parameter instead
* of the first, e.g., @c bind2nd(std::minus(),1.3) will create a
* functor whose @c operator() accepts a floating-point number, subtracts
* 1.3 from it, and returns the result. (If @c bind1st had been used,
* the functor would perform 1.3 - x instead.
*
* Creator-wrapper functions like @c bind1st are intended to be used in
* calling algorithms. Their return values will be temporary objects.
* (The goal is to not require you to type names like
* @c std::binder1st> for declaring a variable to hold the
* return value from @c bind1st(std::plus(),5).
*
* These become more useful when combined with the composition functions.
*
* These functions are deprecated in C++11 and can be replaced by
* @c std::bind (or @c std::tr1::bind) which is more powerful and flexible,
* supporting functions with any number of arguments. Uses of @c bind1st
* can be replaced by @c std::bind(f, x, std::placeholders::_1) and
* @c bind2nd by @c std::bind(f, std::placeholders::_1, x).
