A decorator function like @go could just call os.fork and run the function in the child. We already have a between-process Queue in multiprocessing to use as channels. Or we could have a context manager that forks in __enter__ and waitpids or exits in __exit__. The body of the with-statement would then be executed in the child process, the parent would just raise an exception to skip directly to __exit__. Not rocket science as all. Yes that would give us a new isolated process, but such isolation is present in Erlang as well. (Windows is more tricky though, as there is no efficent fork.) -- http://mail.python.org/mailman/listinfo/python-list
