This is surprising to me. I don't understand either why it doesn't parse, nor your explanation for why it does not parse.

Look at this Spider Monkey session:
js> {"foo": "bar"}
typein:156: SyntaxError: invalid label:
typein:156: {"foo": "bar"}
typein:156: ......^
js> {quz: "quux"}
quux
js> ({quack: "like a duck"}).quack
like a duck
js> ({quack: "like a duck", jump: "like a kangaroo"}).quack
like a duck
js> ({quack: "like a duck", jump: "like a kangaroo"}).jump
like a kangaroo
js> ({"boo": "like a ghost"}).boo
like a ghost
js> ({"boo": "like a ghost", "flash": "like a firefly"}).flash
like a firefly
js> {"boo": "like a ghost"}
typein:165: SyntaxError: invalid label:
typein:165: {"boo": "like a ghost"}
typein:165: ......^

-So to me it appears that there is some grammatical construct which I'm unfamiliar with interfering with the general grammar of object literals. Also, notice these work:

js> x={"boo": "foo"}
[object Object]
js> var y = {"boo": "foo"}
js> y
[object Object]

I guess the next step is to read the javascript grammar to understand what's happening here.
