The problem with that is that the world rejected occam which was the
only rigorous correct implementation of CSP. Unfortunately the go people
didn't really understand CSP, so their channels don't have the right
semantics, and you loose all the correctness properties.
As far as I know, there is no corrrect implentation of CSP in a general
purpose language.
