> Rust can not represent the vast majority of allocations

Do you mean cyclic types?

Rust being low-level, nobody prevents one from implementing garbage-collected types, and I've been looking into this myself: https://github.com/Manishearth/rust-gc

It's "Simple tracing (mark and sweep) garbage collector for Rust", which allows cyclic allocations with simple `Gc<Foo>` syntax. Can't vouch for that implementation, but something like this would be good for many cases.
