I proposed [[GetP]] and [[SetP]] as internal methods because Proxies would "inherit" the built-in behavior for [[Get]] and [[Put]], but "override" the [[GetP]] and [[SetP]] operations. If [[GetP]] and [[SetP]] become abstract operations, won't they need to explicitly dispatch? Proxies could override [[Get]] and [[Put]], but that would require them to duplicate the Object [[Get]] and [[Put]] code. > More generally, I think there should be a 1::1 correspondence between the > internal methods in listed in ES5 Table 8 and fundamental proxy traps. > I absolutely agree we should strive to achieve this.
