> So far as I know, you literally cannot implement a language with mutability on the VM. You could do so, several different ways, e.g.: (1) use the process dictionary, (2) store data transparently to the new language’s user in ets (or, similarly, dets/mnesia), (3) use separate (again, hidden from the language user) Erlang processes for mutable cells. You can't get hig-performance mutability, but you can definitely implement a language with mutability on BEAM. |
