Is this still open because it's possible that it might somehow be
"fixed"? (though as comments note, it doesn't make any sense,
and in any case, in php 5 the reference is unnecessary for the
most common case of returning a new object)
if the idea is to leave it to see how many votes it gets, that
is understandable. otherwise, it would be helpful to close
it as 'not a bug' so people will know they need to change code.
now it's like game of chicken, all wait to see who blinks :)
thx
