Assuming `x` here is the object where "prop" is bound to an accessor, can
you clarify how this would lead to an infinite recursion?
y.prop = 42; // 9.1.9 step 2 binds ownDesc to y's accessor, and calls it in
step 9
super.prop = v; // 9.1.9 step 2 binds ownDesc to x's accessor, and calls it
in step 9
x's setter then runs `v = n;` and the assignment terminates
I must be missing something?
