Bug description: Comparison of scalars & non-scalars w/o typecast should generate an error
Description:
------------
When developing I find that comparison of a scalar and non-scalar is often
unintentional and usually indicates a mistake elsewhere in the program.
It would be nice if comparing scalars and non-scalars generated a
low-priority error message.
Reproduce code:
---------------
<?php
class A {}
$a = new A;
$b = 3;
echo $a > $b;
?>
Expected result:
----------------
Notice: Comparison of scalar and non-scalar without a typecast. in
test.php on line 8
1
Actual result:
--------------
