bind() and argument_type?

I am trying to use bind() with std::not1() (I think this is what I want
to do :-). But std::not1() gets a compiler error because bind doesnt have
an argument_type typedef.

bool is_something( int x, int y )
{
    return something( x, y );
}

{
    ...
    if ( std::not1( boost::bind( is_something, 3, _1 ) ) )
    {
        // not something
    }
}

Am I approaching this incorrectly? Does bind support argument_type?

Thanks for the advice,

 ...Duane
