The following sections have no content:
9.2.5.5 [[Enumerate]] ()
9.2.5.6 [[OwnPropertyKeys]] ()
15.1.0.7 Runtime Semantics: Module Declaration Instantiation
18.2.1.2 Eval Declaration Instantiation
26.2.3 Property of Proxy Instances
Also,
9.2.3.3 [[Enumerate]] ()
9.2.3.4 [[OwnPropertyKeys]] ()
are effectively content-free.
[[Enumerate]] and [[OwnPropertyKeys]] in rev24
15.2.0.15 "Runtime Semantics: Module Declaration Instantiation"
has been marked with an explicit "TO DO" since rev 22
9.4.3.2 "[[Enumerate]] ()"
9.4.3.3 "[[OwnPropertyKeys]] ()"
have content in rev24.
9.4.5.5 "[[Enumerate]] ()"
9.4.5.6 "[[OwnPropertyKeys]] ()"
have content in rev24.
18.2.1.2 "Eval Declaration Instantiation"
Still have no content (and no explicit "TO DO") in rev24,
but Bug 2684 now exists for this.
26.2.3 "Property of Proxy Instances"
section gone since rev21
So I'd say this bug can be closed.
