 Oh goody. The "good" old days, when TRUE did not equal TRUE, are back. :-)

Some old some new.
C and VMS Basic are old.
But some newer script languages also have a
"flexible approach" to true/false.
$ type bool.php
<?php
function test($expr) {
     echo ($expr ? 'true' : 'false') . "\r\n";
}
test(true);
test(false);
test(1);
test(0);
test(-1);
test("X");
test("");
test(null);
?>
$ php bool.php
true
false
true
false
true
true
false
false
