Contacts API -- callers

4.2 Contacts interface

[NoInterfaceObject]
interface Contacts {
    caller void find (DOMString[] fields, ContactFindCB successCB, optional ContactErrorCB errorCB, optional ContactFindOptions options);
};

To quote from WebIDL, http://dev.w3.org/2006/webapi/WebIDL/Overview.html#idl-callers

Specifications SHOULD NOT use callers unless required to specify the behavior of legacy APIs. (emphasis theirs, not mine)

Callable objects step outside the semantics of ECMAScript and can't be self-hosted.

I would much prefer if we drop the caller annotation here. Any objections?
