I'd argue that one should check that a variable is of an expected type, or maybe cast the type
to the expected one, before using it.
I vote for "Not a bug".

Description:
------------
If you try to access an undefined index on an array, you will get an error. But if you try the same
on bool(false) PHP will silently accept it and ignores the error.
Please note that this is especially dangerous on database results, where you get false instead of an
array when there is no result.
If you try the same on a valid array with an invalid index you will get a E_NOTICE.
So trying to use the array operator on a non-array should at least raise an E_STRICT error,
indicating that there is a problem, instead of silently continuing to use the wrong result for
further calculations.
Test script:
---------------
$array1 = false;
$array2 = array('a'=>3);
echo 5+3*$array1['a']; // output: 5
var_dump($array1['b']); // output: NULL
var_dump($array2['b']); // output: <b>Notice</b>: Undefined index: b
