Hi -- I'm very new to Ruby. I would like to start attending your informal meetings on Thursday evenings. In the meantime, I'm wondering if anyone can explain...

Well, it's too late to accept any more RSVPs. Officially, I'm cancelling the meeting. If anybody still shows up and still wants to hang out that's fine, but...
... That's disappointing. I was planning on making this my first meeting. However, it sounds like there is going to be no one there. Hopefully there will be...

HI Doug: As Kevin ('sup? How's life in the Bay now?) pointed out, case uses the === operator and thus is quite a bit more powerful than the switch statements...
