Why Scalar Type Hints? What is the goal?

- Hints for IDEs - autocompletion?
- Find bugs with static program analysis?
- Find bugs at runtime?
- Help improving the quality of PHP applications
   - with notices?
   - with errors?
   - with ...?
- ...?

Validation of HTML form input is strict. If I know that
$_POST['age'] contains a positive integer why should
foo(int $age) then able to accept float -123.42?
