Arrays to scalars already fail. See
http://wiki.php.net/rfc/typecheckingstrictandweak#current_behavior_of_zend_parse_parameters

<?php
var_dump(strtoupper(array("abc")));

gives:
Warning: `strtoupper()` expects parameter 1 to be string, array given in ...
on line 2
 `NULL` 

To respond to Jordi Boggiano, I am not advocating changing the behavior of
cast, only of internal functions' argument parsing.

Also, I think it doesn't make sense to allow "17.", but disallow "17.5"
when an int is expected. See floating point arithmetic and equality
comparisons.
