Isn't that just erlang?

Snarkiness aside, that would be interesting. Not just as an educational tool, but it might be useful in the same way as erlang is (large, fault-tolerant, massively parallel systems). But with OOP instead of FP (Elixir attempts to be the "friendly"/more conventional version of erlang, but it is still very much a functional language).

The nice thing about doing a Smalltalk is that there is a colossal amount of software built on top of it. I'd love to know how much of that corpus could operate like this. I don't recall ever using locks, but I also never ran ST on a multicore machine either. It's just that the message-passing idea matches a many-core machine so well it's a shame not to play with it.
