Comment 1 Ian 'Hixie' Hickson 2013-03-06 22:36:58 UTC 
It is by far not the only one, and personally I think it _is_ preferred. :-)
Comment 2 Anne 2013-03-07 11:06:34 UTC 
It is the only one. Point me to another IDL block.
Comment 3 Ian 'Hixie' Hickson 2013-04-12 23:06:22 UTC 
DOMStringMap, DOMElementMap, and Storage, at least, all have deleters.
Comment 4 Ian 'Hixie' Hickson 2013-04-12 23:10:59 UTC 
(Not to mention Object and Array, of course.)
Comment 5 Anne 2013-04-13 08:14:39 UTC 
WebIDL distinguishes between "indexed property deleters" and "named property deleters". This is the only example of the former.
Comment 6 Ian 'Hixie' Hickson 2013-04-24 00:38:17 UTC 
Even if we only look at deleters that take numeric inputs, Array has one.

But I don't understand why we would. What's the relevant difference? Just because these are indexed by number rather than string, they shouldn't be deletable? A deleter is a deleter, why care what the type of the argument is, other than for internal WebIDL reasons.
Comment 7 Cameron McCormack 2013-04-24 01:07:11 UTC 
Arrays can be sparse.  Other APIs don't allow sparse indexed properties.  I don't think we want to make our APIs have sparse indexed properties, and I also don't think we want to have the properties "shift over" to fill in the gap.
Comment 8 Ian 'Hixie' Hickson 2013-04-27 00:00:59 UTC 
I guess the shifting over behaviour is unusual. Fair enough.

It seems the non-normative green box was not updated. It still mentions:
- delete items[index]
But does not mention:
- remove(index)
