There is another language called "V language". There the author 
claims that the language will feature some kind static analysis 
of lifetimes like Rust but also reference counting. The compiler 
tries to do static analysis in order to figure out when an object 
goes out of scope. If the compiler fails, it will just add 
reference counting to the object. This approach is kind of 
transparent saves you from the explicitness of Rust but do 
optimizes where it can. This is just according to he author but 
so far an idea without any realization yet. I don't know how 
similar this approach is to Swift. I'm just guessing here but I 
think this is where we are heading when it comes to memory 
management.

Reference counting is usually completely ok for systems 
programming but it would be nice to have this kind of 
optimization.
