I have a class that's operating on a socket.

I'd like to have simple operations on that socket like "list
configured hosts", "allow connection to host", etc.  And I'd like them
to be decorated with "reconnected_to_server_if_needed".

I'll probably end up putting a try/except in each simple operation,
making them a bit less simple.
