And how do I specify an optional array of Bar or null? The whole concept of allowing null members seems to completely defeat the purpose of the ArrayOf hint for me. I can understand wanting to make the parameter optional, but I cannot see a use case for null members from the point of view of the caller. I never null out members of an array, I only omit them from the declaration or remove the member from the array via e.g. unset() or stack operations (pop(), shift() etc). YMMV of course, but for me allowing null members just makes the callee's life more difficult and does not gain anything.
