Hi!

It's about the perception of consistency. "Oh, I can do this! Neat:" function neat(Foo | Bar $a) { ... }

You shouldn't be able to do this, because it makes no sense - why would a function accept two random types and only them? That's probably a bad design - it should be one type or two functions.

I detailed use cases for both & and | here: http://news.php.net/php.internals/92335 Admittedly Foo|Bar is of limited use, although there is some use. Foo&Bar, however, has plenty of uses. I do agree with the sentiment that having Foo|Bar for catch but not for function signatures is going to confuse people. If nothing else, it will result in even more pressure to add union types. --Larry Garfield
