I'm playing with the 4.3 Mac Demo.snap image. I'm looking at the tutorial there. I've created lots of slots. I'm seeing how Morphic in that tutorial is similar to the Morphic I've used (but not programmed) in Squeak. It's all pretty cool.
I'd really like to say to somebody: "You know, you JS programmer you. Your conception of how to use JS sucks. The reason is you don't understand prototypical inheritance. Here's what you need to know..."
And then a light would go on over their head, and they'd use JS the way it's meant to instead of the hack that it usually is.
I'm going to read the Wiki page on Prototype-based programming, but anything you could contribute would be great.
