Ok, well after concurrency was out of the picture.

Ain't that the truth. Talk about books with long-term influence. Along
with the Smalltalk issue of Byte, and Ted Nelson's Dream Machines. :-)

I periodically think about what it would look like, and work like, to
combine Erlang's core constructs and plumbing (which I continue to think
of as actors) with a Smalltalk like environment (inspectors, browsers,
In theory, there is no difference between theory and practice.
