Erlang is weird in this regard. It has very strong guarantees when it comes to per-process heap that make GC much simpler: no escape hatches for mutability when most immutable languages do include them! But on the other hand inter-process communication is a form of mutability (using another process as a global mutable variable is trivial) and ETS etc. present a mutable interface.
