26)  http://heycam.github.io/webidl/#es-iterators says that for indexed props
%ArrayProto_values% is used unless there is an explicit iterable declaration,
in which case the default iterator object is used (and its behavior needs to be
defined).  But http://heycam.github.io/webidl/#idl-iterable says that if you
have both an iterable declaration and indexed props then the indexed prop
values get iterated.  These are contradicting each other and we should decide
which behavior we actually want.  See bug 23212 comment 4 for the relevant spec
