Could you provide more information? How does this fail? Do you have
an example?
As far as I can tell, this is working as intended. Using a trunk build:
V8 version 0.3.4.1
> var cache = {}
> function getCacheForID(id) { return cache[id] = cache[id] || {}; }
> getCacheForID('asdf').x = 42
42
> getCacheForID('qwer').x = 1
1
> getCacheForID('asdf').x
42
> getCacheForID('qwer').x
