I agree it's a bit awkward learning to read every Clause 15 method spec 
in terms of the Clause 15 intro's subtle language about missing 
arguments. Kind of a pain, really. But in the interest of a minimal 
spec, to avoid redundancy that can then mutate and diverge, making spec 
bugs, we generally try to hoist such common "code", if you will.

Do you think a specific change should be made for Object.is, or for all 
method specs in 15?
