Well, this is not correct: the BEAM nowhere specifies that its
instruction set has to be implemented using a private heap architecture.
In fact, we successfully used the BEAM instruction set to implement
both a shared heap and a hybrid heap implementation. See:
> So on an implementation with a single heap all data is shared. Now there aren't currently many single heap implementations, to be exact only one, erjang (Erlang on the JVM). :-)
There have been more. We had an OTP system with a shared heap and the
hybrid heap system was part of OTP for quite a while. IMO, it's too bad
that it was not maintained when Erlang/OTP was extended to support SMP
Also, the ETOS (Erlang to Scheme) system was based on a shared heap
