This is something we've seen any time we've done storage or message passing, that one of the first thing authors ask for is to not have to do JSON serialization/parsing manually. The ability to pass ArrayBuffers and Blobs is somewhat less commonly asked for, likely because binary data is less often used, but seems important nonetheless. We can't allow transferring of objects, since you can't transfer something to all listeners of a broadcasting API. But plain structured clones should be no problem to support conceptually (though more work to implement of course). We've started looking at doing structured clone support for Firefox and likely won't ship until we have that implemented. 104211 1 ian 2014-04-22 20:44:36 +0000 Yeah that makes a lot of sense. For some reason when speccing the first draft of this I forgot we could clone without supporting transfers. 104765 2 contributor 2014-04-30 00:14:08 +0000 Checked in as WHATWG revision r8590.
