Hi Chriss,
> Is this for HEAD or .16? what modules does it affect?
its for HEAD only, I will not touch 0.9.16, except the core team decides
that
I should do these things there also.
All modules have been affected.

Unknown, but I found this within the code and removed the reference fom the
call.
Best would be when the reference in the call would be ignored, because it is
deprecated.

Thats right, but all changes have been done in head only, head is for
development,
so this is a problem of the developer of third party code.
But here is a small Test script including Results:
<?php
function test(&$param1,&$param2)
{
++$param2;
echo ':' . $param1 . ':' . $param2 . ":<br />\n";
}
$strpara = 'test';
$numpara = 0;
test($strpara,$numpara);
echo $numpara . ":<br />\n";
test(&$strpara,&$numpara);
echo $numpara . ":<br />\n";
?>
Running under php 4.3.11 and 5.0.4 produces the correct results!
So you don need to worry.

Depends on the functions body, when the body modifies the variables content,
this modification will be visible to the caller.

I think its not a question of missing features, more of malworked code.
What I can say from the code examination is, that the color alternation of
tables might not work. (for example).
