Current spec says select the sequence<> overload, and it what at least Gecko
implements.  I haven't checked other browsers offhand...

I have no problem with converting platform objects that have indexed properties
to sequences.  I don't even have a problem with doing it for platform objects
that _don't_ have indexed properties.  Given that overload resolution and union
subtype conversions define an order in which you try things, I don't really see
a problem with having two things that can both convert to sequence be
distinguishable.  After all, we distinguish between all sorts of stuff that can
convert to string!
