I don't have any opinion yet.
I guess I didn't know that I was "misusing" bind(). Anyway, I find it
wrong
that
bind(foo,_1)(i) and bind(foo,i)() differs.
Naturally it has to differ.
bind(foo,i) needs to take a copy of i,
or we wouldn't be able to do things like:
int square(int);
function<void(void)> f(int x)
   {
       return bind(square, x * 5);
   }
My point is that if the prototype was

void square( int& );

then

function< void(void) > f( int x )
{
   return bind( square, x*5 );
}

should not compile. It should only compile with a call to
ref().
