[boost] [bind] error in docs?

In the paragraph "Limitations", where the forwarding
problem is discussed, the following appears:

"...An oft-proposed "solution" to this problem is to add
an overload: 

template<class T> void f(T & t);
template<class T> void f(T const & t);

Unfortunately, this (a) requires providing 512 overloads
for nine arguments and (b) does not actually work for
const arguments, both l- and r-values, since the two
templates produce the exact same signature and cannot be
partially ordered."

It's asserion (b) that puzzles me. Doesn't the standard
say that the second overload of f is more specialized
thus yielding a well-defined partial order? This tricky
businesses always elude me, so I might be totally
wrong, of course :)
