This allows you to express bind( f, x, y, z ), which was impossible before, 
but you've now lost the capability to express bind( f, x, y, _1 ), which 
was.

bind( f, _1, y, z ), which is often needed in practice, is possible under 
neither, which makes me view this whole exercise as somewhat academic.
