type-hinting is asserting.
checking of types is needed only on interface-border points (where
With strict checking, that means instead of calling:
foo($bar);
you'd have now to do:
if(is_integer($bar)) {
// stupid foo() call would blow up if passed not integer, so I have
to manually handle it
// oh wait, actually I don't have any way to handle it - I need
foo() to be called to proceed
// so let's just
die("can't call foo() because \$bar is not integer");
}
foo($bar);
Now how it's easier or makes application more stable? What happens if
foo() is changed and now accepts both integers and strings? What happens
if someone forgets to write a wrapper?
