I don't have a strong opinion on this since I don't really need it, but using a cast expression feels a bit wrong. Not sure if we want to keep the option open of having operator overloading, but what about something like: string foo <= bar; or string foo << bar; > > * `unowned' type modifier complements `weak' type modifier > > `weak' only make sense for reference fields, list elements, and local > variables to break reference cycles.

However, I fear a bit that many people will turn to using pointers when this is also applied to local variables. > In other places where `weak' is currently used such as method return > values or fields of non reference counted types, it has the meaning of > "no ownership transfer".

It probably depends how you look at it. Personally, I tend to think in terms of shared and weak references. Owned and unowned seem to suggest an object can only be owned in one place.
