The work-around is to call the original value of Object.getOwnPropertyDescriptor and query the properties of the resulting object (e.g. enumerable:false --> kJSPropertyAttributeDontEnum), but that's not so nice. 248807 1 kent.hansen 2010-07-09 00:58:50 -0700 This relates to https://bugs.webkit.org/show_bug.cgi?id=41769 577714 2 barraclough 2012-03-13 13:09:02 -0700 The JSC API should probably offer a low-level API of reflection traps matching set of 9 traps in 8.12 - e.g. we should have something matching [[GetOwnProperty]], which would return a descriptor. We may also want to consider any new reflection APIs being introduced in ES6 (e.g. direct proxies) in designing any API here.
