Consider also the way the spec could read.  For example, for the
'Error' object, instead of having "19.5.1.1 Error ( message )" and
"19.5.1.2 new Error ( ...argumentsList )", in Jason's formulation
section 19.5.1.2 would just be "Error[ @@new ]]", aka an ordinary
method definition.  "If Error is implemented as an ECMAScript function
object, its inherited implementation of @@new will perform the above
steps."
