I know I have no karma here, but anyway:

If you want to give people a hinting they access their stuff in a
wrong way *and* you want it in a consistent way:

why not throw an E_STRICT (or maybe even an E_NOTICE) when accessing anything
via [] that is not array?

$a = null; $a['foo']; -> should give an E_STRICT (if not an E_NOTICE)
$a = false; $a['foo']; -> should give an E_STRICT (if not an E_NOTICE)
$a = "FOO"; $a['foo']; -> should give an E_STRICT (if not an E_NOTICE)
$a = array(); $a['foo']; -> gives an E_NOTICE because of "undefined index 'foo'"
$a = array('foo'=>'FOO'); $a['foo'] -> obviously okay

just my few p.
