Precisely, it would cause a vast amount of headaches for many projects.
Think of user input where you are expecting an integer and it must be a
positive integer (which would ultimately be a string); it is much faster to
do a quick check such as:
$foo = (int) $_GET['foo'];
if ($foo > 0) {
....
}
I'd personally not have to wrap more items around it due to a notice or
warning.
