Never mind, it's not a big problem. :-)

Hey, when using the @ operator that index is NOT added to the array!
Good: it's almost the same result of isset(). :-)

I hadn't tried that code before because, as far as I *knew*, the @
operator only suppressed notices, while the real problem was that
byRef() was adding the index to the array, besides raising the notice.

I'm now asking myself if this is not a bug - an undocumented feature. :)

Thanks to all for your answer.
