Hi Stas:

To me, this is the bug.  $a['blah'] does not exist.  An undefined index
notice should be raised.  The key "blah" should not be converted to 0.
The following two things should behave the same:

$b = array('exists' => 'foo');
echo $b['blah'] . "\n";

$a = 'foo';
echo $a['blah'] . "\n";

But that second one echos out "f".  This is a huge WTF.

Thanks,
