Rust has GC, i.e. reference counting. This is also often required 
with multiple ownership which you often end up with in data 
structures. I would rather say GC is mandatory in Rust, unless 
you want to take the unsafe approach.

It's a matter what you regard as GC. Is only tracing GC regarded 
as true GC?
