*shrug* If you want things to be mutable between functions, stick an & in front of them; if you
want copy-on-write performance, leave it to the engine. That doesn't seem to have anything to
do with JSON or API as a use case.

That gives us all the more reason to look for efficient ways of populating anonymous class
instances, then. (And, indeed, populating actual named classes, if such a penalty applies to them
too.)
My point was that if we didn't already have it, making (object)$array create an instance of an
anonymous class would feel natural and not lose anything that we have now.
I see stdClass as a badly named and no longer necessary kludge, and would rather see features that
help replace it than features that rely on it.
