When a similar anomaly involving the ! operator was reported (http://bugs.php.net/bug.php?id=17180), the response was that PHP is "smart" about such things and invokes the DWIM principle to silently alter the precedence of = in certain situations. This resulted in the addition of a note to the end of the operator precedence page at http://uk2.php.net/manual/en/language.operators.php#language.operators.precedence, but it seems to me that this is too specific to the ! operator and should be generalized. In fact, I'd completely forgotten that I suggested as much at the end of the bug report -- but this hasn't been taken up, so maybe a bunch of you want to re-activate the bug report and support my suggestion??
