Do not use :: -- it is wanted for
http://wiki.ecmascript.org/doku.php?id=strawman:guards (and used previously in
E4X, ECMA-357).
Allen presented new syntax roughly as verbose at the March TC39 meeting.
General reaction was "too verbose".
Wherefore the #!~ prefixes idea, now in
http://wiki.ecmascript.org/doku.php?id=harmony:object_literals -- the syntax
there is definitely not final, BTW, but something like it is needed. I've
argued we shouldn't try to be "half-verbose", and since ES5 has the very
verbose functional API, object initialisers probably will go the other way.
