[Boost-users] [signals] Disconnecting slots

In the docs for signals, an example is given for disconnecting slots:

  void foo();
  void bar();

  signal<void()> sig;

  sig.connect(&foo);
  sig.connect(&bar);

  // disconnects foo, but not bar
  sig.disconnect(&foo);

When I try this with MSV 7.1, I get an compiler error:

error C2664:
'boost::signal0<R,Combiner,Group,GroupCompare,SlotFunction>::disconnect'
: 
  cannot convert parameter 1 from 'void (__cdecl *)(void)' to 'const 
  boost::signal0<R,Combiner,Group,GroupCompare,SlotFunction>::group_type
&'
    with
    [
      R=boost::detail::function_traits_helper<boost::add_pointer<void
(void)>::type>::result_type,
      Combiner=boost::last_value<void>,
      Group=int,
      GroupCompare=std::less<int>,
      SlotFunction=boost::function<void (void)>
    ]
    and
    [
      R=boost::detail::function_traits_helper<boost::add_pointer<void
(void)>::type>::result_type,
      Combiner=boost::last_value<void>,
      Group=int,
      GroupCompare=std::less<int>,
      SlotFunction=boost::function<void (void)>
    ]

My question is, are the docs incorrect, or am I doing something wrong?

Joes.
