Re: [RFC][DISCUSSION] Object type hint

I can see uses for it, although none of them are impossible without the object typehint - they currently do an is_object() check. In the same way that Iterable type hint allows you to safely do a foreach on an argument, object allows you to safely use property accessor syntax (i.e. ->). For me it would be most useful in lower level utility classes.
