Description:
------------
What are the chances of changing the way in which switch case-matching works, from a '=='-equivalent to a '==='-equivalent?

Alternatively, how about a huge warning on the manual page for the switch statement for people who might reasonably expect that the attached code would act in a sane fashion?


Reproduce code:
---------------
switch (null)
{
case 0:
    echo "PHP case-matching is brain-damaged.\n";
    break;
case null:
    echo "PHP case-matching is sane.\n";
    break;
}


Expected result:
----------------
PHP case-matching is sane.


Actual result:
--------------
PHP case-matching is brain-damaged.
