Agreed, though implementation-wise, there is another technique for
determining whether the use provided an argument to timeout or not...

sentinel = object()

def connect(HOST, PORT, timeout=sentinel):
    ...
    if timeout is not sentinel:
        sock.settimeout(timeout)
    ...

A keyword argument via **kwargs is also fine.  I have no preference.
