Is there a reason you sent this to v8-dev instead of v8-users like your previous message? I've taken the liberty of moving v8-dev to BCC. To answer your question: you can use a->StrictEquals(b) or a->SameValue(b). If you are looking for a unique value that you can use as a key in a set or map, you're out of luck: functions have identity but not (partial or total) ordering. You can of course store them in a hash map and use a mix of GetIdentityHash() and SameValue() to retrieve them in (on average) better than linear time. -- -- v8-dev mailing list v8-dev@googlegroups.com http://groups.google.com/group/v8-dev --- You received this message because you are subscribed to the Google Groups "v8-dev" group.
