You may be passing an object to a function that again calls a piece of library code using type hints (but you don't have to know that). If your object is of the wrong type, PHP dies. PEAR packages follow a strict "stay alive" policy, so this would not be acceptable for a PEAR package. In other words, PEAR can not use type hints if they may cause PHP to exit. - Stig
