[Twisted-Python] What the hell?

From tcp.py: ============ class Client(Connection): """A client for TCP (and similiar) sockets. """ def __init__(self, host, port, protocol): """Initialize the client, setting up its socket, and request to connect. """ if host == 'unix': # "port" in this case is really a filename ... ============ That is sooo wrong. What if my computer is named 'unix'? Why does the TCP code deal with files?
