It is greatly simplified by automatic memory management. Rust doesn't have 
a GC, but it has a complex ownership system instead, and that's the basis 
of its memory management. When that's insufficient, you use reference 
counting.

Besides which, this is about defaults. In cases where your data is 
actually mutable and it would be awkward to switch to a more Haskell-like 
way of coding, you can still use that.
