foreach only allowed variables to be traversed by reference. This never
really made sense because
a) Expressions like array(&$a, &$b) can be meaningfully iterated by-ref
b) Function calls can return by-ref (so they can also be meaningfully
iterated)
c) Iterators could at least in theory also be iterated by-ref (not
sure if any iterator makes use of this)
With by-ref generators the restriction makes even less sense, so I removed
it altogether.
