yes, well we quite got off topic by claiming that now in php 5 referencing
literally is not needed. and that, i believe, was a tangent that you
provided...and then boldly asked for examples of, which both micha and i
gave to you. and now, you want to get back into an isolated instance that
doesn't require it. we call that a 'strawman'.
if you keep making sweeping statements that are not true about php, i'll be
happy to continually thwart them. i suppose that's why you killfile me. and
even though you may, everyone else can read all the posts. that kind of puts
you at a disadvantage. ;^)
