I will stop the over-citing madness here and now :-P.

The struggle to formalize ArrayLike, which seems like a common goal  
for ES the core language and for WebIDL's ES bindings, makes me want  
to give an exception to the "catchalls considered harmful for new  
interfaces" injunction. I agree that indexing into array-likes, with  
no liveness magic, seems containable and desirable. ES folks haven't  
nailed down ArrayLike yet (our fault) and we would benefit from  
collaboration with WebIDL folks here.

So if you are doing more ArrayLike interfaces, let's keep talking.  
Don't let at least my catchalls-considered-harmful statements stop  
progress on ArrayLikes.

I expect some ES folks may demur now :-).
