Description:
------------
it is possible to lint PHP script, and be warned about usage of 'int' or 'float' but not 'object'.


with 'class int', php -l yields : 
Cannot use 'int' as class name as it is reserved 

with 'class object', php -l yields : 
No syntax errors detected

Test script:
---------------
<?php

class int {}

class object {}

?>

Expected result:
----------------
Consistent error message with 'int' at linting time : 

Cannot use 'object' as class name as it is reserved 


Actual result:
--------------
No syntax errors detected
