smalltalk was originally the entire stack, from the hardware all the way up, i agree that for a long time, it lived in a weird in between world where it was sort of an OS and sort of not. working out how to keep what makes 'smalltalk smalltalk' while ironing out those issues is something that both redline and pharo are trying to solve from different angles.

i'm interested in hearing more about the taking tips from erlang idea. i'd love to chat more via email:
