I don't particularly mind either way. It's a bit like a game.. we can make our own rules, as long as we're playing by the same rules. > Code, as you say, should be written as much as possible in decoupled units > that can be tested in isolation.

The only point to consider is whether the implementation will also be faster and more reliable. I'm sure you all can do the latter.. just something to keep in mind. gustavo @ http://niemeyer.net -- Juju-dev mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/juju-dev
