Description Ben Kelly 2014-06-24 21:26:08 UTC
Currently the fetch spec is proposing webidl that looks like:

  typedef (Headers or sequence<sequence<ByteString>> or OpenEndedDictionary<ByteString>) HeadersInit;

This is illegal at the moment, however, because Sequence and OpenEndedDictionary are not distinguishable.
Comment 1 Boris Zbarsky 2014-06-24 21:33:09 UTC
In particular, we should try to convert as sequence; if that fails due to non-iterable, then go on to OpenEndedDictionary (or dictionary, for that matter).
