Too much, Too little

Objective-C 2.0 has completely changed the game (and rendered most of the earlier gdb tricks mentioned to no longer work as well). That said, it has also added some pretty slick new features that I hope I'll be able to give justice to once I get some more free time and some more coherent thoughts.

Just thought I'd let y'all know where things were.

Best console log message ever

I was put between a rock and a hard place. Basically, I had to call a method on a class that isn't exported (i.e. I'm in plugin-space, and it needs to invoke something on an application-internal class that isn't exported). Through some trickery, I was able to get it working (man I love objective-C!). However, inserting the plugin into an application that doesn't have such a class results in an amazing console error that I've never seen before:

that "trouble ahead" part is awesome. I think it happens to any OC object that doesn't inherit from NSObject, but gets treated like it does. Fun stuff, that :)
