Requesting that will at least require a major-release (f.e. PHP 6.0) ... but I would rather request
to add a notice or warning to the documentation of references to remind stuff like that.
http://www.php.net/manual/en/language.references.php
I think this is stuff more people will stumble over ...

I agree it would be wrong to change php's handling of call by reference in foreach loops
because there may be a need to access that reference after completing the loop. I was going to
suggest there should be a warning in the manual to unset the reference after the foreach loop is
completed, but I see the current online manual has that warning prominently displayed on the foreach
page. I had a version of the manual from July last year that didn't have the warning, so
I'll update my local manual and make sure I keep it up to date. Lesson learned (both manual and
foreach references).
Cheers
Arno
